4.2.4:
Features added
* Allow using pkg-config for build configuration.
Bugs fixed
* Crash when moving an element to another document with
Element.insert().
|
|
4.2.3:
Reverted GH-265: lxml links against zlib as a shared library again.
|
|
4.2.2:
Bugs fixed
* GH266: Fix sporadic crash during GC when parse-time schema validation is used
and the parser participates in a reference cycle.
* GH265: lxml no longer links against zlib as a shared library, only on static builds.
|
|
4.2.1:
Bugs fixed
* iterwalk() failed to return the ‘start’ event for the initial element if a tag selector is used.
* Failure to import 4.2.0 into PyPy due to a missing library symbol.
* Add “-isysroot” linker option on MacOS as needed by XCode 9.
|
|
4.2.0:
Features added
* SelectElement.value returns more standard-compliant and browser-like defaults for non-multi-selects. If no option is selected, the value of the first option is returned (instead of None). If multiple options are selected, the value of the last one is returned (instead of that of the first one). If no options are present (not standard-compliant) SelectElement.value still returns None.
* The HTMLParser() now supports the huge_tree option. Patch by stranac.
Bugs fixed
* Some XSLT messages were not captured by the transform error log.
* Crash at shutdown after an interrupted iterparse run with XMLSchema validation.
|
|
4.1.1:
* Rebuild with Cython 0.27.3 to improve support for Py3.7.
|
|
4.1.0:
Features added
* ElementPath supports text predicates for current node, like “[.=’text’]”.
* ElementPath allows spaces in predicates.
* Custom Element classes and XPath functions can now be registered with a decorator rather than explicit dict assignments.
* Static Linux wheels are now built with link time optimisation (LTO) enabled. This should have a beneficial impact on the overall performance by providing a tighter compiler integration between lxml and libxml2/libxslt.
Bugs fixed
* Requesting non-Element objects like comments from a document with PythonElementClassLookup could fail with a TypeError.
|
|
|
|
4.0.0:
Features added
--------------
* The ElementPath implementation is now compiled using Cython,
which speeds up the ``.find*()`` methods quite significantly.
* The modules ``lxml.builder``, ``lxml.html.diff`` and ``lxml.html.clean``
are also compiled using Cython in order to speed them up.
* ``xmlfile()`` supports async coroutines using ``async with`` and ``await``.
* ``iterwalk()`` has a new method ``skip_subtree()`` that prevents walking into
the descendants of the current element.
* ``RelaxNG.from_rnc_string()`` accepts a ``base_url`` argument to
allow relative resource lookups.
* The XSLT result object has a new method ``.write_output(file)`` that serialises
output data into a file according to the ``<xsl:output>`` configuration.
Bugs fixed
----------
* GH-251: HTML comments were handled incorrectly by the soupparser.
Patch by mozbugbox.
* LP-1654544: The html5parser no longer passes the ``useChardet`` option
if the input is a Unicode string, unless explicitly requested. When parsing
files, the default is to enable it when a URL or file path is passed (because
the file is then opened in binary mode), and to disable it when reading from
a file(-like) object.
Note: This is a backwards incompatible change of the default configuration.
If your code parses byte strings/streams and depends on character detection,
please pass the option ``guess_charset=True`` explicitly, which already worked
in older lxml versions.
* LP-1703810: ``etree.fromstring()`` failed to parse UTF-32 data with BOM.
* LP-1526522: Some RelaxNG errors were not reported in the error log.
* LP-1567526: Empty and plain text input raised a TypeError in soupparser.
* LP-1710429: Uninitialised variable usage in HTML diff.
* LP-1415643: The closing tags context manager in ``xmlfile()`` could continue
to output end tags even after writing failed with an exception.
* LP-1465357: ``xmlfile.write()`` now accepts and ignores None as input argument.
* Compilation under Py3.7-pre failed due to a modified function signature.
Other changes
-------------
* The main module source files were renamed from ``lxml.*.pyx`` to plain
``*.pyx`` (e.g. ``etree.pyx``) to simplify their handling in the build
process. Care was taken to keep the old header files as fallbacks for
code that compiles against the public C-API of lxml, but it might still
be worth validating that third-party code does not notice this change.

Features added
--------------
* ``ElementTree.write()`` has a new option ``doctype`` that writes out a
doctype string before the serialisation, in the same way as ``tostring()``.
* GH-220: ``xmlfile`` allows switching output methods at an element level.
Patch by Burak Arslan.
* LP-1595781, GH-240: added a PyCapsule Python API and C-level API for
passing externally generated libxml2 documents into lxml.
* GH-244: error log entries have a new property ``path`` with an XPath
expression (if known, None otherwise) that points to the tree element
responsible for the error. Patch by Bob Kline.
* The namespace prefix mapping that can be used in ElementPath now injects
a default namespace when passing a None prefix.
Bugs fixed
----------
* GH-238: Character escapes were not hex-encoded in the ``xmlfile`` serialiser.
Patch by matejcik.
* GH-229: fix for externally created XML documents. Patch by Theodore Dubois.
* LP-1665241, GH-228: Form data handling in lxml.html no longer strips the
option values specified in form attributes but only the text values.
Patch by Ashish Kulkarni.
* LP-1551797: revert previous fix for XSLT error logging as it breaks
multi-threaded XSLT processing.
* LP-1673355, GH-233: ``fromstring()`` html5parser failed to parse byte strings.
Other changes
-------------
* The previously undocumented ``docstring`` option in ``ElementTree.write()``
produces a deprecation warning and will eventually be removed.
|
|
Bugs fixed
* GH-218 was ineffective in Python 3.
* GH-222: lxml.html.submit_form() failed in Python 3.

disabling the automatic doctype creation. Patch by Shadab Zafar.
* GH#201: Calling the method ``.set('attrname')`` without value argument
(or ``None``) on HTML elements creates an attribute without value that
serialises like ``<div attrname></div>``. Patch by Daniel Holth.
* GH#197: Ignore form input fields in ``form_values()`` when they are
marked as ``disabled`` in HTML. Patch by Kristian Klemon.
Bugs fixed
----------
* GH#206: File name and line number were missing from XSLT error messages.
Patch by Marcus Brinkmann.
Other changes
-------------
* Log entries no longer allow anything but plain string objects as message text
and file name.
* ``zlib`` is included in the list of statically built libraries.

|
|
|
|
3.6.1 (2016-07-24)
==================
Features added
--------------
* GH#180: Separate option ``inline_style`` for Cleaner that only removes ``style``
attributes instead of all styles. Patch by Christian Pedersen.
* GH#196: Windows build support for Python 3.5. Contribution by Maximilian Hils.
Bugs fixed
----------
* GH#199: Exclude ``file`` fields from ``FormElement.form_values`` (as browsers do).
Patch by Tomas Divis.
* GH#198, LP#1568167: Try to provide base URL from ``Resolver.resolve_string()``.
Patch by Michael van Tellingen.
* GH#191: More accurate float serialisation in ``objectify.FloatElement``.

Patch by Armin Rigo.
* GH#186: Soupparser failed to process entities in Python 3.x.
Patch by Duncan Morris.
* GH#185: Rare encoding related `TypeError` on import was fixed.
Patch by Petr Demin.

Bugs fixed
----------
* Unicode string results failed XPath queries in PyPy.
* LP#1497051: HTML target parser failed to terminate on exceptions
and continued parsing instead.
* Deprecated API usage in doctestcompare.
3.5.0b1 (2015-09-18)
====================
Features added
--------------
* ``cleanup_namespaces()`` accepts a new argument ``keep_ns_prefixes``
that does not remove definitions of the provided prefix-namespace
mapping from the tree.
* ``cleanup_namespaces()`` accepts a new argument ``top_nsmap`` that
moves definitions of the provided prefix-namespace mapping to the
top of the tree.
* LP#1490451: ``Element`` objects gained a ``cssselect()`` method as
known from ``lxml.html``. Patch by Simon Sapin.
* API functions and methods behave and look more like Python functions,
which allows introspection on them etc. One side effect to be aware of
is that the functions now bind as methods when assigned to a class
variable. A quick fix is to wrap them in ``staticmethod()`` (as for
normal Python functions).
* ISO-Schematron support gained an option ``error_finder`` that allows
passing a filter function for picking validation errors from reports.
* LP#1243600: Elements in ``lxml.html`` gained a ``classes`` property
that provides a set-like interface to the ``class`` attribute.
Original patch by masklinn.
* LP#1341964: The soupparser now handles DOCTYPE declarations, comments
and processing instructions outside of the root element.
Patch by Olli Pottonen.
* LP#1421512: The ``docinfo`` of a tree was made editable to allow
setting and removing the public ID and system ID of the DOCTYPE.
Patch by Olli Pottonen.
* LP#1442427: More work-arounds for quirks and bugs in pypy and pypy3.
* ``lxml.html.soupparser`` now uses BeautifulSoup version 4 instead
of version 3 if available.
Bugs fixed
----------
* Memory errors that occur during tree adaptations (e.g. moving subtrees
to foreign documents) could leave the tree in a crash prone state.
* Calling ``process_children()`` in an XSLT extension element without
an ``output_parent`` argument failed with a ``TypeError``.
Fix by Jens Tröger.
* GH#162: Image data in HTML ``data`` URLs is considered safe and
no longer removed by ``lxml.html.clean`` JavaScript cleaner.
* GH#166: Static build could link libraries in wrong order.
* GH#172: Rely a bit more on libxml2 for encoding detection rather than
rolling our own in some cases. Patch by Olli Pottonen.
* GH#159: Validity checks for names and string content were tightened
to detect the use of illegal characters early. Patch by Olli Pottonen.
* LP#1421921: Comments/PIs before the DOCTYPE declaration were not
serialised. Patch by Olli Pottonen.
* LP#659367: Some HTML DOCTYPE declarations were not serialised.
Patch by Olli Pottonen.
* LP#1238503: lxml.doctestcompare is now consistent with stdlib's doctest
in how it uses ``+`` and ``-`` to refer to unexpected and missing output.
* Empty prefixes are explicitly rejected when a namespace mapping is used
with ElementPath to avoid hiding bugs in user code.
* Several problems with PyPy were fixed by switching to Cython 0.23.

|
3.4.4 (2015-04-25)
==================
Bugs fixed
----------
* An ElementTree compatibility test added in lxml 3.4.3 that failed in
Python 3.4+ was removed again.
|
|
3.4.3 (2015-04-15)
==================
Bugs fixed
----------
* Expression cache in ElementPath was ignored. Fix by Changaco.
* LP#1426868: Passing a default namespace and a prefixed namespace mapping
as nsmap into ``xmlfile.element()`` raised a ``TypeError``.
* LP#1421927: DOCTYPE system URLs were incorrectly quoted when containing
double quotes. Patch by Olli Pottonen.
* LP#1419354: meta-redirect URLs were incorrectly processed by
``iterlinks()`` if preceded by whitespace.
|
|
3.4.2 (2015-02-07)
==================
Bugs fixed
----------
* LP#1415907: Crash when creating an XMLSchema from a non-root element
of an XML document.
* LP#1369362: HTML cleaning failed when hitting processing instructions
with pseudo-attributes.
* ``CDATA()`` wrapped content was rejected for tail text.
* CDATA sections were not serialised as tail text of the top-level element.
|
|
3.4.1 (2014-11-20)
==================
Features added
--------------
* New ``htmlfile`` HTML generator to accompany the incremental ``xmlfile``
serialisation API. Patch by Burak Arslan.
Bugs fixed
----------
* ``lxml.sax.ElementTreeContentHandler`` did not initialise its superclass.
|
|
3.4.0 (2014-09-10)
==================
Features added
--------------
* ``xmlfile(buffered=False)`` disables output buffering and flushes the
content after each API operation (starting/ending element blocks or writes).
A new method ``xf.flush()`` can alternatively be used to explicitly flush
the output.
* ``lxml.html.document_fromstring`` has a new option ``ensure_head_body=True``
which will add an empty head and/or body element to the result document if
missing.
* ``lxml.html.iterlinks`` now returns links inside meta refresh tags.
* New ``XMLParser`` option ``collect_ids=False`` to disable ID hash table
creation. This can substantially speed up parsing of documents with many
different IDs that are not used.
* The parser uses per-document hash tables for XML IDs. This reduces the
load of the global parser dict and speeds up parsing for documents with
many different IDs.
* ``ElementTree.getelementpath(element)`` returns a structural ElementPath
expression for the given element, which can be used for lookups later.
* ``xmlfile()`` accepts a new argument ``close=True`` to close file(-like)
objects after writing to them. Before, ``xmlfile()`` only closed the file
if it had opened it internally.
* Allow "bytearray" type for ASCII text input.
Bugs fixed
----------
Other changes
-------------
* LP#400588: decoding errors have become hard errors even in recovery mode.
Previously, they could lead to an internal tree representation in a mixed
encoding state, which lead to very late errors or even silently incorrect
behaviour during tree traversal or serialisation.
* Requires Python 2.6, 2.7, 3.2 or later. No longer supports
Python 2.4, 2.5 and 3.1, use lxml 3.3.x for those.
* Requires libxml2 2.7.0 or later and libxslt 1.1.23 or later,
use lxml 3.3.x with older versions.
|
|
3.3.6 (2014-08-28)
==================
Bugs fixed
----------
* Prevent tree cycle creation when adding Elements as siblings.
* LP#1361948: crash when deallocating Element siblings without parent.
* LP#1354652: crash when traversing internally loaded documents in XSLT
extension functions.
|
|
3.3.5 (2014-04-18)
==================
Bugs fixed
----------
* HTML cleaning could fail to strip javascript links that mix control
characters into the link scheme.
|
|
3.3.4 (2014-04-03)
==================
Features added
--------------
* Source line numbers above 65535 are available on Elements when
using libxml2 2.9 or later.
Bugs fixed
----------
* ``lxml.html.fragment_fromstring()`` failed for bytes input in Py3.
|
|
3.3.3 (2014-03-04)
==================
Bugs fixed
----------
* Crash when using Element subtypes with ``__slots__``.
Other changes
-------------
* The internal classes ``_LogEntry`` and ``_Attrib`` can no longer be
subclassed from Python code.
3.3.2 (2014-02-26)
==================
Bugs fixed
----------
* The properties ``resolvers`` and ``version``, as well as the methods
``set_element_class_lookup()`` and ``makeelement()``, were lost from
``iterparse`` objects in 3.3.0.
* LP#1222132: instances of ``XMLSchema``, ``Schematron`` and ``RelaxNG``
did not clear their local ``error_log`` before running a validation.
* LP#1238500: lxml.doctestcompare mixed up "expected" and "actual" in
attribute values.
* Some file I/O tests were failing in MS-Windows due to non-portable temp
file usage. Initial patch by Gabi Davar.
* LP#910014: duplicate IDs in a document were not reported by DTD validation.
* LP#1185332: ``tostring(method="html")`` did not use HTML serialisation
semantics for trailing tail text. Initial patch by Sylvain Viollon.
* LP#1281139: ``.attrib`` value of Comments lost its mutation methods
in 3.3.0. Even though it is empty and immutable, it should still
provide the same interface as that returned for Elements.
|
|
3.3.1 (2014-02-12)
==================
Features added
--------------
Bugs fixed
----------
* LP#1014290: HTML documents parsed with ``parser.feed()`` failed to find
elements during tag iteration.
* LP#1273709: Building in PyPy failed due to missing support for
``PyUnicode_Compare()`` and ``PyByteArray_*()`` in PyPy's C-API.
* LP#1274413: Compilation in MSVC failed due to missing "stdint.h" standard
header file.
* LP#1274118: iterparse() failed to parse BOM prefixed files.
|
|
3.3.0 (2014-01-26)
==================
Bugs fixed
----------
* The heuristic that distinguishes file paths from URLs was tightened
to produce less false negatives.
3.3.0beta5 (2014-01-18)
=======================
Features added
--------------
* The PEP 393 unicode parsing support gained a fallback for wchar strings
which might still be somewhat common on Windows systems.
Bugs fixed
----------
* Several error handling problems were fixed throughout the code base that
could previously lead to exceptions being silently swallowed or not
properly reported.
* The C-API function ``appendChild()`` is now deprecated as it does not
propagate exceptions (its return type is ``void``). The new function
``appendChildToElement()`` was added as a safe replacement.
* Passing a string into ``fromstringlist()`` raises an exception instead of
parsing the string character by character.
Other changes
-------------
* Document cleanup code was simplified using the new GC features in
Cython 0.20.
3.3.0beta4 (2014-01-12)
=======================
Bugs fixed
----------
* The (empty) value returned by the ``attrib`` property of Entity and Comment
objects was mutable.
* Element class lookup wasn't available for the new pull parsers or when using
a custom parser target.
* Setting Element attributes on instantiation with both the ``attrib`` argument
and keyword arguments could modify the mapping passed as ``attrib``.
* LP#1266171: DTDs instantiated from internal/external subsets (i.e. through
the docinfo property) lost their attribute declarations.
Other changes
-------------
* Built with Cython 0.20pre (gitrev 012ae82eb) to prepare support for
Python 3.4.
3.3.0beta3 (2014-01-02)
=======================
Features added
--------------
* Unicode string parsing was optimised for Python 3.3 (PEP 393).
Bugs fixed
----------
* HTML parsing of Unicode strings could misdecode the input on some platforms.
* Crash in xmlfile() when closing open elements out of order in an error case.
3.3.0beta2 (2013-12-20)
=======================
Features added
--------------
* ``iterparse()`` supports the ``recover`` option.
Bugs fixed
----------
* Crash in ``iterparse()`` for HTML parsing.
* Crash in target parsing with attributes.
Other changes
-------------
* The safety check in the read-only tree implementation (e.g. used by
``PythonElementClassLookup``) raises a more appropriate ``ReferenceError``
for illegal access after tree disposal instead of an ``AssertionError``.
This should only impact test code that specifically checks the original
behaviour.
3.3.0beta1 (2013-12-12)
=======================
Features added
--------------
* New option ``handle_failures`` in ``make_links_absolute()`` and
``resolve_base_href()`` (lxml.html) that enables ignoring or
discarding links that fail to parse as URLs.
* New parser classes ``XMLPullParser`` and ``HTMLPullParser`` for
incremental parsing, as implemented for ElementTree in Python 3.4.
* ``iterparse()`` enables recovery mode by default for HTML parsing
(``html=True``).
Bugs fixed
----------
* LP#1255132: crash when trying to run validation over non-Element (e.g.
comment or PI).
* Error messages in the log and in exception messages that originated
from libxml2 could accidentally be picked up from preceding warnings
instead of the actual error.
* The ``ElementMaker`` in lxml.objectify did not accept a dict as
argument for adding attributes to the element it's building. This
works as in lxml.builder now.
* LP#1228881: ``repr(XSLTAccessControl)`` failed in Python 3.
* Raise ``ValueError`` when trying to append an Element to itself or
to one of its own descendants, instead of running into an infinite
loop.
* LP#1206077: htmldiff discarded whitespace from the output.
* Compressed plain-text serialisation to file-like objects was broken.
* lxml.html.formfill: Fix textarea form filling.
The textarea used to be cleared before the new content was set,
which removed the name attribute.
Other changes
-------------
* Some basic API classes use freelists internally for faster
instantiation. This can speed up some ``iterparse()`` scenarios,
for example.
* ``iterparse()`` was rewritten to use the new ``*PullParser``
classes internally instead of being a parser itself.
3.2.5 (2014-01-02)
==================
Bugs fixed
----------
* Crash in xmlfile() when closing open elements out of order in an error case.
* Crash in target parsing with attributes.
* LP#1255132: crash when trying to run validation over non-Element (e.g.
comment or PI).

3.2.2 (2013-07-28)
==================
Features added
--------------
Bugs fixed
----------
* LP#1185701: spurious XMLSyntaxError after finishing iterparse().
* Crash in lxml.objectify during xsi annotation.
Other changes
-------------
* Return values of user provided element class lookup methods are now
validated against the type of the XML node they represent to prevent
API class mismatches.
|
|
|
|
3.2.1 (2013-05-11)
==================
Features added
--------------
* The methods ``apply_templates()`` and ``process_children()`` of XSLT
extension elements have gained two new boolean options ``elements_only``
and ``remove_blank_text`` that discard either all strings or whitespace-only
strings from the result list.
Bugs fixed
----------
* When moving Elements to another tree, the namespace cleanup mechanism
no longer drops namespace prefixes from attributes for which it finds
a default namespace declaration, to prevent them from appearing as
unnamespaced attributes after serialisation.
* Returning non-type objects from a custom class lookup method could lead
to a crash.
* Instantiating and using subtypes of Comments and ProcessingInstructions
crashed.
Other changes
-------------
3.2.0 (2013-04-28)
==================
Features added
--------------
Bugs fixed
----------
* LP#690319: Leading whitespace could change the behaviour of the string
parsing functions in ``lxml.html``.
* LP#599318: The string parsing functions in ``lxml.html`` are more robust
in the face of uncommon HTML content like framesets or missing body tags.
Patch by Stefan Seelmann.
* LP#712941: I/O errors while trying to access files with paths that contain
non-ASCII characters could raise ``UnicodeDecodeError`` instead of properly
reporting the ``IOError``.
* LP#673205: Parsing from in-memory strings disabled network access in the
default parser and made subsequent attempts to parse from a URL fail.
* LP#971754: lxml.html.clean appends 'nofollow' to 'rel' attributes instead
of overwriting the current value.
* LP#715687: lxml.html.clean no longer discards scripts that are explicitly
allowed by the user provided whitelist. Patch by Christine Koppelt.

3.1.2 (2013-04-12)
==================
Features added
--------------
Bugs fixed
----------
* LP#1136509: Passing attributes through the namespace-unaware API of
the sax bridge (i.e. the ``handler.startElement()`` method) failed
with a ``TypeError``. Patch by Mike Bayer.
* LP#1123074: Fix serialisation error in XSLT output when converting
the result tree to a Unicode string.
* GH#105: Replace illegal usage of ``xmlBufLength()`` in libxml2 2.9.0
by properly exported API function ``xmlBufUse()``.

3.1.1 (2013-03-29)
==================
Features added
--------------
Bugs fixed
----------
* LP#1160386: Write access to ``lxml.html.FormElement.fields`` raised
an AttributeError in Py3.
* Illegal memory access during cleanup in incremental xmlfile writer.
Other changes

3.1.0 (2013-02-10)
==================
Features added
--------------
* GH#89: lxml.html.clean allows overriding the set of attributes that it
considers 'safe'. Patch by Francis Devereux.
Bugs fixed
----------
* LP#1104370: ``copy.copy(el.attrib)`` raised an exception. It now returns
a copy of the attributes as a plain Python dict.
* GH#95: When used with namespace prefixes, the ``el.find*()`` methods
always used the first namespace mapping that was provided for each
path expression instead of using the one that was actually passed
in for the current run.
* LP#1092521, GH#91: Fix undefined C symbol in Python runtimes compiled
without threading support. Patch by Ulrich Seidl.
Other changes
-------------
3.1beta1 (2012-12-21)
=====================
Features added
--------------
* New build-time option ``--with-unicode-strings`` for Python 2 that
makes the API always return Unicode strings for names and text
instead of byte strings for plain ASCII content.
* New incremental XML file writing API ``etree.xmlfile()``.
* E factory in lxml.objectify is callable to simplify the creation of
tags with non-identifier names without having to resort to getattr().
Bugs fixed
----------
* When starting from a non-namespaced element in lxml.objectify, searching
for a child without explicitly specifying a namespace incorrectly found
namespaced elements with the requested local name, instead of restricting
the search to non-namespaced children.
* GH#85: Deprecation warnings were fixed for Python 3.x.
* GH#33: lxml.html.fromstring() failed to accept bytes input in Py3.
* LP#1080792: Static build of libxml2 2.9.0 failed due to missing file.
Other changes
-------------
* The externally useless class ``_ObjectifyElementMakerCaller`` was
removed from the module API of lxml.objectify.
* LP#1075622: lxml.builder is faster for adding text to elements with
many children. Patch by Anders Hammarquist.

|
* Fix crash during interpreter shutdown by switching to Cython 0.17.3 for building.

Mark as python3-ready.
3.0.1 (2012-10-14)
==================
Bugs fixed
----------
* LP#1065924: Element proxies could disappear during garbage collection
in PyPy without proper cleanup.
* GH#71: Failure to work with libxml2 2.6.x.
* LP#1065139: static MacOS-X build failed in Py3.
3.0 (2012-10-08)
================
Bugs fixed
----------
* End-of-file handling was incorrect in iterparse() when reading from
a low-level C file stream and failed in libxml2 2.9.0 due to its
improved consistency checks.
Other changes
-------------
* The build no longer uses Cython by default unless the generated C files
are missing. To use Cython, pass the option "--with-cython". To ignore
the fatal build error when Cython is required but not available (e.g. to
run special setup.py commands that do not actually run a build), pass
"--without-cython".
3.0beta1 (2012-09-26)
=====================
Features added
--------------
* Python level access to (optional) libxml2 memory debugging features
to simplify debugging of memory leaks etc.
Bugs fixed
----------
* Fix a memory leak in XPath by switching to Cython 0.17.1.
* Some tests were adapted to work with PyPy.
Other changes
-------------
* The code was adapted to work with the upcoming libxml2 2.9.0 release.
3.0alpha2 (2012-08-23)
======================
Features added
--------------
* The ``.iter()`` method of elements now accepts ``tag`` arguments like
``"{*}name"`` to search for elements with a given local name in any
namespace. With this addition, all combinations of wildcards now work
as expected:
``"{ns}name"``, ``"{}name"``, ``"{*}name"``, ``"{ns}*"``, ``"{}*"``
and ``"{*}*"``. Note that ``"name"`` is equivalent to ``"{}name"``,
but ``"*"`` is ``"{*}*"``.
The same change applies to the ``.getiterator()``, ``.itersiblings()``,
``.iterancestors()``, ``.iterdescendants()``, ``.iterchildren()``
and ``.itertext()`` methods;the ``strip_attributes()``,
``strip_elements()`` and ``strip_tags()`` functions as well as the
``iterparse()`` class.
* C14N allows specifying the inclusive prefixes to be promoted
to top-level during exclusive serialisation.
Bugs fixed
----------
* Passing long Unicode strings into the ``feed()`` parser interface
failed to read the entire string.
3.0alpha1 (2012-07-31)
======================
Features added
--------------
* Initial support for building in PyPy (through cpyext).
* DTD objects gained an API that allows read access to their
declarations.
* ``xpathgrep.py`` gained support for parsing line-by-line (e.g.
from grep output) and for surrounding the output with a new root
tag.
* ``E-factory`` in ``lxml.builder`` accepts subtypes of known data
types (such as string subtypes) when building elements around them.
* Tree iteration and ``iterparse()`` with a selective ``tag``
argument supports passing a set of tags. Tree nodes will be
returned by the iterators if they match any of the tags.
Bugs fixed
----------
* The ``.find*()`` methods in ``lxml.objectify`` no longer use XPath
internally, which makes them faster in many cases (especially when
short circuiting after a single or couple of elements) and fixes
some behavioural differences compared to ``lxml.etree``. Note that
this means that they no longer support arbitrary XPath expressions
but only the subset that the ``ElementPath`` language supports.
The previous implementation was also redundant with the normal
XPath support, which can be used as a replacement.
* ``el.find('*')`` could accidentally return a comment or processing
instruction that happened to be in the wrong spot. (Same for the
other ``.find*()`` methods.)
* The error logging is less intrusive and avoids a global setup where
possible.
* Fixed undefined names in html5lib parser.
* ``xpathgrep.py`` did not work in Python 3.
* ``Element.attrib.update()`` did not accept an ``attrib`` of
another Element as parameter.
* For subtypes of ``ElementBase`` that make the ``.text`` or ``.tail``
properties immutable (as in objectify, for example), inserting text
when creating Elements through the E-Factory feature of the class
constructor would fail with an exception, stating that the text
cannot be modified.
Other changes
--------------
* The code base was overhauled to properly use 'const' where the API
of libxml2 and libxslt requests it. This also has an impact on the
public C-API of lxml itself, as defined in ``etreepublic.pxd``, as
well as the provided declarations in the ``lxml/includes/`` directory.
Code that uses these declarations may have to be adapted. On the
plus side, this fixes several C compiler warnings, also for user
code, thus making it easier to spot real problems again.
* The functionality of "lxml.cssselect" was moved into a separate PyPI
package called "cssselect". To continue using it, you must install
that package separately. The "lxml.cssselect" module is still
available and provides the same interface, provided the "cssselect"
package can be imported at runtime.
* Element attributes passed in as an ``attrib`` dict or as keyword
arguments are now sorted by (namespaced) name before being created
to make their order predictable for serialisation and iteration.
Note that adding or deleting attributes afterwards does not take
that order into account, i.e. setting a new attribute appends it
after the existing ones.
* Several classes that are for internal use only were removed
from the ``lxml.etree`` module dict:
``_InputDocument, _ResolverRegistry, _ResolverContext, _BaseContext,
_ExsltRegExp, _IterparseContext, _TempStore, _ExceptionContext,
__ContentOnlyElement, _AttribIterator, _NamespaceRegistry,
_ClassNamespaceRegistry, _FunctionNamespaceRegistry,
_XPathFunctionNamespaceRegistry, _ParserDictionaryContext,
_FileReaderContext, _ParserContext, _PythonSaxParserTarget,
_TargetParserContext, _ReadOnlyProxy, _ReadOnlyPIProxy,
_ReadOnlyEntityProxy, _ReadOnlyElementProxy, _OpaqueNodeWrapper,
_OpaqueDocumentWrapper, _ModifyContentOnlyProxy,
_ModifyContentOnlyPIProxy, _ModifyContentOnlyEntityProxy,
_AppendOnlyElementProxy, _SaxParserContext, _FilelikeWriter,
_ParserSchemaValidationContext, _XPathContext,
_XSLTResolverContext, _XSLTContext, _XSLTQuotedStringParam``
* Several internal classes can no longer be inherited from:
``_InputDocument, _ResolverRegistry, _ExsltRegExp, _ElementUnicodeResult,
_IterparseContext, _TempStore, _AttribIterator, _ClassNamespaceRegistry,
_XPathFunctionNamespaceRegistry, _ParserDictionaryContext,
_FileReaderContext, _PythonSaxParserTarget, _TargetParserContext,
_ReadOnlyPIProxy, _ReadOnlyEntityProxy, _OpaqueDocumentWrapper,
_ModifyContentOnlyPIProxy, _ModifyContentOnlyEntityProxy,
_AppendOnlyElementProxy, _FilelikeWriter, _ParserSchemaValidationContext,
_XPathContext, _XSLTResolverContext, _XSLTContext, _XSLTQuotedStringParam,
_XSLTResultTree, _XSLTProcessingInstruction``
2.3.6 (2012-09-28)
==================
Bugs fixed
----------
* Passing long Unicode strings into the ``feed()`` parser interface
failed to read the entire string.
2.3.5 (2012-07-31)
==================
Bugs fixed
----------
* Crash when merging text nodes in ``element.remove()``.
* Crash in sax/target parser when reporting empty doctype.
2.3.4 (2012-03-26)
==================
Bugs fixed
----------
* Crash when building an nsmap (Element property) with empty
namespace URIs.
* Crash due to race condition when errors (or user messages) occur
during threaded XSLT processing.
* XSLT stylesheet compilation could ignore compilation errors.
2.3.3 (2012-01-04)
==================
Features added
--------------
* ``lxml.html.tostring()`` gained new serialisation options
``with_tail`` and ``doctype``.
Bugs fixed
----------
* Fixed a crash when using ``iterparse()`` for HTML parsing and
requesting start events.
* Fixed parsing of more selectors in cssselect. Whitespace before
pseudo-elements and pseudo-classes is significant as it is a
descendant combinator.
"E :pseudo" should parse the same as "E \*:pseudo", not "E:pseudo".
Patch by Simon Sapin.
* lxml.html.diff no longer raises an exception when hitting
'img' tags without 'src' attribute.

|
|
|
2.3.2 (2011-11-11)
==================
Features added
--------------
* ``lxml.objectify.deannotate()`` has a new boolean option
``cleanup_namespaces`` to remove the objectify namespace
declarations (and generally clean up the namespace declarations)
after removing the type annotations.
* ``lxml.objectify`` gained its own ``SubElement()`` function as a
copy of ``etree.SubElement`` to avoid an otherwise redundant import
of ``lxml.etree`` on the user side.
Bugs fixed
----------
* Fixed the "descendant" bug in cssselect a second time (after a first
fix in lxml 2.3.1). The previous change resulted in a serious
performance regression for the XPath based evaluation of the
translated expression. Note that this breaks the usage of some of
the generated XPath expressions as XSLT location paths that
previously worked in 2.3.1.
* Fixed parsing of some selectors in cssselect. Whitespace after combinators
">", "+" and "~" is now correctly ignored. Previously is was parsed as
a descendant combinator. For example, "div> .foo" was parsed the same as
"div>* .foo" instead of "div>.foo".
Other changes
--------------
2.3.1 (2011-09-25)
==================
Features added
--------------
* New option ``kill_tags`` in ``lxml.html.clean`` to remove specific
tags and their content (i.e. their whole subtree).
* ``pi.get()`` and ``pi.attrib`` on processing instructions to parse
pseudo-attributes from the text content of processing instructions.
* ``lxml.get_include()`` returns a list of include paths that can be
used to compile external C code against lxml.etree. This is
specifically required for statically linked lxml builds when code
needs to compile against the exact same header file versions as lxml
itself.
* ``Resolver.resolve_file()`` takes an additional option
``close_file`` that configures if the file(-like) object will be
closed after reading or not. By default, the file will be closed,
as the user is not expected to keep a reference to it.
Bugs fixed
----------
* HTML cleaning didn't remove 'data:' links.
* The html5lib parser integration now uses the 'official'
implementation in html5lib itself, which makes it work with newer
releases of the library.
* In ``lxml.sax``, ``endElementNS()`` could incorrectly reject a plain
tag name when the corresponding start event inferred the same plain
tag name to be in the default namespace.
* When an open file-like object is passed into ``parse()`` or
``iterparse()``, the parser will no longer close it after use. This
reverts a change in lxml 2.3 where all files would be closed. It is
the users responsibility to properly close the file(-like) object,
also in error cases.
* Assertion error in lxml.html.cleaner when discarding top-level elements.
* In lxml.cssselect, use the xpath 'A//B' (short for
'A/descendant-or-self::node()/B') instead of 'A/descendant::B' for
the css descendant selector ('A B'). This makes a few edge cases
like ``"div *:last-child"`` consistent with the selector behavior in
WebKit and Firefox, and makes more css expressions valid location
paths (for use in xsl:template match).
* In lxml.html, non-selected ``<option>`` tags no longer show up in the
collected form values.
* Adding/removing ``<option>`` values to/from a multiple select form
field properly selects them and unselects them.
Other changes
--------------
* Static builds can specify the download directory with the
``--download-dir`` option.
2.3 (2011-02-06)
================
Features added
--------------
* When looking for children, ``lxml.objectify`` takes '{}tag' as
meaning an empty namespace, as opposed to the parent namespace.
Bugs fixed
----------
* When finished reading from a file-like object, the parser
immediately calls its ``.close()`` method.
* When finished parsing, ``iterparse()`` immediately closes the input
file.
* Work-around for libxml2 bug that can leave the HTML parser in a
non-functional state after parsing a severly broken document (fixed
in libxml2 2.7.8).
* ``marque`` tag in HTML cleanup code is correctly named ``marquee``.
Other changes
--------------
* Some public functions in the Cython-level C-API have more explicit
return types.
2.3beta1 (2010-09-06)
=====================
Features added
--------------
Bugs fixed
----------
* Crash in newer libxml2 versions when moving elements between
documents that had attributes on replaced XInclude nodes.
* ``XMLID()`` function was missing the optional ``parser`` and
``base_url`` parameters.
* Searching for wildcard tags in ``iterparse()`` was broken in Py3.
* ``lxml.html.open_in_browser()`` didn't work in Python 3 due to the
use of os.tempnam. It now takes an optional 'encoding' parameter.
Other changes
--------------
2.3alpha2 (2010-07-24)
======================
Features added
--------------
Bugs fixed
----------
* Crash in XSLT when generating text-only result documents with a
stylesheet created in a different thread.
Other changes
--------------
* ``repr()`` of Element objects shows the hex ID with leading 0x
(following ElementTree 1.3).
2.3alpha1 (2010-06-19)
======================
Features added
--------------
* Keyword argument ``namespaces`` in ``lxml.cssselect.CSSSelector()``
to pass a prefix-to-namespace mapping for the selector.
* New function ``lxml.etree.register_namespace(prefix, uri)`` that
globally registers a namespace prefix for a namespace that newly
created Elements in that namespace will use automatically. Follows
ElementTree 1.3.
* Support 'unicode' string name as encoding parameter in
``tostring()``, following ElementTree 1.3.
* Support 'c14n' serialisation method in ``ElementTree.write()`` and
``tostring()``, following ElementTree 1.3.
* The ElementPath expression syntax (``el.find*()``) was extended to
match the upcoming ElementTree 1.3 that will ship in the standard
library of Python 3.2/2.7. This includes extended support for
predicates as well as namespace prefixes (as known from XPath).
* During regular XPath evaluation, various ESXLT functions are
available within their namespace when using libxslt 1.1.26 or later.
* Support passing a readily configured logger instance into
``PyErrorLog``, instead of a logger name.
* On serialisation, the new ``doctype`` parameter can be used to
override the DOCTYPE (internal subset) of the document.
* New parameter ``output_parent`` to ``XSLTExtension.apply_templates()``
to append the resulting content directly to an output element.
* ``XSLTExtension.process_children()`` to process the content of the
XSLT extension element itself.
* ISO-Schematron support based on the de-facto Schematron reference
'skeleton implementation'.
* XSLT objects now take XPath object as ``__call__`` stylesheet
parameters.
* Enable path caching in ElementPath (``el.find*()``) to avoid parsing
overhead.
* Setting the value of a namespaced attribute always uses a prefixed
namespace instead of the default namespace even if both declare the
same namespace URI. This avoids serialisation problems when an
attribute from a default namespace is set on an element from a
different namespace.
* XSLT extension elements: support for XSLT context nodes other than
elements: document root, comments, processing instructions.
* Support for strings (in addition to Elements) in node-sets returned
by extension functions.
* Forms that lack an ``action`` attribute default to the base URL of
the document on submit.
* XPath attribute result strings have an ``attrname`` property.
* Namespace URIs get validated against RFC 3986 at the API level
(required by the XML namespace specification).
* Target parsers show their target object in the ``.target`` property
(compatible with ElementTree).
Bugs fixed
----------
* API is hardened against invalid proxy instances to prevent crashes
due to incorrectly instantiated Element instances.
* Prevent crash when instantiating ``CommentBase`` and friends.
* Export ElementTree compatible XML parser class as
``XMLTreeBuilder``, as it is called in ET 1.2.
* ObjectifiedDataElements in lxml.objectify were not hashable. They
now use the hash value of the underlying Python value (string,
number, etc.) to which they compare equal.
* Parsing broken fragments in lxml.html could fail if the fragment
contained an orphaned closing '</div>' tag.
* Using XSLT extension elements around the root of the output document
crashed.
* ``lxml.cssselect`` did not distinguish between ``x[attr="val"]`` and
``x [attr="val"]`` (with a space). The latter now matches the
attribute independent of the element.
* Rewriting multiple links inside of HTML text content could end up
replacing unrelated content as replacements could impact the
reported position of subsequent matches. Modifications are now
simplified by letting the ``iterlinks()`` generator in ``lxml.html``
return links in reversed order if they appear inside the same text
node. Thus, replacements and link-internal modifications no longer
change the position of links reported afterwards.
* The ``.value`` attribute of ``textarea`` elements in lxml.html did
not represent the complete raw value (including child tags etc.). It
now serialises the complete content on read and replaces the
complete content by a string on write.
* Target parser didn't call ``.close()`` on the target object if
parsing failed. Now it is guaranteed that ``.close()`` will be
called after parsing, regardless of the outcome.
Other changes
-------------
* Official support for Python 3.1.2 and later.
* Static MS Windows builds can now download their dependencies
themselves.
* ``Element.attrib`` no longer uses a cyclic reference back to its
Element object. It therefore no longer requires the garbage
collector to clean up.
* Static builds include libiconv, in addition to libxml2 and libxslt.
2.2.8 (2010-09-02)
==================
Bugs fixed
----------
* Crash in newer libxml2 versions when moving elements between
documents that had attributes on replaced XInclude nodes.
* Import fix for urljoin in Python 3.1+.
2.2.7 (2010-07-24)
==================
Bugs fixed
----------
* Crash in XSLT when generating text-only result documents with a
stylesheet created in a different thread.
|
|
|
|
2.2.6 (2010-03-02)
==================
Bugs fixed
----------
* Fixed several Python 3 regressions by building with Cython 0.11.3.
2.2.5 (2010-02-28)
==================
Features added
--------------
* Support for running XSLT extension elements on the input root node
(e.g. in a template matching on "/").
Bugs fixed
----------
* Crash in XPath evaluation when reading smart strings from a document
other than the original context document.
* Support recent versions of html5lib by not requiring its
``XHTMLParser`` in ``htmlparser.py`` anymore.
* Manually instantiating the custom element classes in
``lxml.objectify`` could crash.
* Invalid XML text characters were not rejected by the API when they
appeared in unicode strings directly after non-ASCII characters.
* lxml.html.open_http_urllib() did not work in Python 3.
* The functions ``strip_tags()`` and ``strip_elements()`` in
``lxml.etree`` did not remove all occurrences of a tag in all cases.
* Crash in XSLT extension elements when the XSLT context node is not
an element.
