</a>
</p>
<p>Libxml2 is the XML C parser and toolkit developed for the Gnome project
(but usable outside of the Gnome platform), it is free software available
under the
<a href="http://www.opensource.org/licenses/mit-license.html">MIT
License
</a>
. XML itself is a metalanguage to design markup languages, i.e.
text language where semantic and structure are added to the content using
extra "markup" information enclosed between angle brackets. HTML is the most
well-known markup language. Though the library is written in C
<a href="python.html">a variety of language bindings
</a>
make it available in
other environments.
</p>
<p>Libxml2 is known to be very portable, the library should build and work
without serious troubles on a variety of systems (Linux, Unix, Windows,
CygWin, MacOS, MacOS X, RISC Os, OS/2, VMS, QNX, MVS, ...)

Working Draft 7
April 2004
</li>
</ul>
<p>In most cases libxml2 tries to implement the specifications in a
relatively strictly compliant way. As of release 2.4.16, libxml2 passes all
1800+ tests from the
<a href="http://www.oasis-open.org/committees/xml-conformance/">OASIS XML Tests
Suite
</a>
.
</p>
<p>To some extent libxml2 provides support for the following additional
specifications but doesn't claim to implement them completely:
</p>
<ul> <li>Document Object Model (DOM)
<a href="http://www.w3.org/TR/DOM-Level-2-Core/">http://www.w3.org/TR/DOM-Level-2-Core/
</a>
it doesn't implement the API itself, gdome2 does this on top of
libxml2
</li>
<li> <a href="http://www.cis.ohio-state.edu/rfc/rfc959.txt">RFC 959
</a>
:
libxml2 implements a basic FTP client code
</li>
<li> <a href="http://www.cis.ohio-state.edu/rfc/rfc1945.txt">RFC 1945
</a>
:
HTTP/1.0, again a basic HTTP client code
</li>
<li>SAX: a minimal SAX implementation compatible with early expat
versions
</li>
<li>DocBook SGML v4: libxml2 includes a hackish parser to transition to
XML
</li>
</ul>
<p>A partial implementation of
<a href="http://www.w3.org/TR/2001/REC-xmlschema-1-20010502/">XML Schemas Part
1: Structure
</a>
is being worked on but it would be far too early to make any
conformance statement about it at the moment.
</p>
<p>Separate documents:
</p>
<ul> <li> <a href="http://xmlsoft.org/XSLT/">the libxslt page
</a>
providing an
implementation of XSLT 1.0 and common extensions like EXSLT for
libxml2
</li>
<li> <a href="http://www.cs.unibo.it/~casarini/gdome2/">the gdome2 page
</a>
: a standard DOM2 implementation for libxml2
