+.SH "INTRODUCTION"
+
+.PP
+The xmllint program parses one or more XML files, specified on the command line as \fIxmlfile\fR\&. It prints various types of output, depending upon the options selected\&. It is useful for detecting errors both in XML code and in the XML parser itself\&.
+
+.PP
+It is included in libxml2\&.
+
+.SH "OPTIONS"
+
+.TP
+\fB\-\-version\fR
+Display the version of libxml2 used\&.
+
+.TP
+\fB\-\-debug\fR
+Parse a file and output an annotated tree of the in\-memory version of the document\&.
+
+.TP
+\fB\-\-shell\fR
+Run a navigating shell\&. Details on available commands in shell mode are below\&.
+
+.TP
+\fB\-\-debugent\fR
+Debug the entities defined in the document\&.
+
+.TP
+\fB\-\-copy\fR
+Test the internal copy implementation\&.
+
+.TP
+\fB\-\-recover\fR
+Output any parsable portions of an invalid document\&.
+
+.TP
+\fB\-\-noent\fR
+Substitute entity values for entity references\&. By default, xmllint leaves entity references in place\&.
+
+.TP
+\fB\-\-nocdata\fR
+Substitute CDATA section by equivalent text nodes\&.
+
+.TP
+\fB\-\-nsclean\fR
+Remove redundant namespace declarations\&.
+
+.TP
+\fB\-\-noout\fR
+Suppress output\&. By default, xmllint outputs the result tree\&.
+
+.TP
+\fB\-\-htmlout\fR
+Output results as an HTML file\&. This causes xmllint to output the necessary HTML tags surrounding the result tree output so the results can be displayed in a browser\&.
+
+.TP
+\fB\-\-nowrap \fR
+Do not output HTML doc wrapper\&.
+
+.TP
+\fB\-\-valid \fR
+Determine if the document is a valid instance of the included Document Type Definition (DTD)\&. A DTD to be validated against also can be specified at the command line using the \fB\-\-dtdvalid\fR option\&. By default, xmllint also checks to determine if the document is well\-formed\&.
+
+.TP
+\fB\-\-postvalid\fR
+Validate after parsing is completed\&.
+
+.TP
+\fB\-\-dtdvalid\fR \fIURL\fR
+Use the DTD specified by \fIURL\fR for validation\&.
+
+.TP
+\fB\-\-dtdvalidfpi\fR \fIFPI\fR
+Use the DTD specified by the Public Identifier \fIFPI\fR for validation, note that this will require a Catalog exporting that Public Identifier to work\&.
+
+.TP
+\fB\-\-timing\fR
+Output information about the time it takes xmllint to perform the various steps\&.
+
+.TP
+\fB\-\-repeat\fR
+Repeat 100 times, for timing or profiling\&.
+
+.TP
+\fB\-\-insert\fR
+Test for valid insertions\&.
+
+.TP
+\fB\-\-compress\fR
+Turn on gzip compression of output\&.
+
+.TP
+\fB\-\-html\fR
+Use the HTML parser\&.
+
+.TP
+\fB\-\-push\fR
+Use the push mode of the parser\&.
+
+.TP
+\fB\-\-memory\fR
+Parse from memory\&.
+
+.TP
+\fB\-\-nowarning\fR
+Do not emit warnings from the parser and/or validator\&.
+
+.TP
+\fB\-\-noblanks\fR
+Drop ignorable blank spaces\&.
+
+.TP
+\fB\-\-format\fR
+Reformat and reindent the output\&. The $XMLLINT_INDENT environment variable controls the indentation (default value is two spaces " ")\&.
+
+.TP
+\fB\-\-testIO\fR
+Test user input/output support\&.
+
+.TP
+\fB\-\-encode\fR \fIencoding\fR
+Output in the given encoding\&.
+
+.TP
+\fB\-\-catalogs\fR
+Use the catalogs from $SGML_CATALOG_FILES\&. Otherwise /etc/xml/catalog is used by default\&.
+
+.TP
+\fB\-\-nocatalogs\fR
+Do not use any catalogs\&.
+
+.TP
+\fB\-\-auto\fR
+Generate a small document for testing purposes\&.
+
+.TP
+\fB\-\-xinclude\fR
+Do XInclude processing\&.
+
+.TP
+\fB\-\-loaddtd\fR
+Fetch external DTD\&.
+
+.TP
+\fB\-\-dtdattr\fR
+Fetch external DTD and populate the tree with inherited attributes\&.
+
+.TP
+\fB\-\-dropdtd\fR
+Remove DTD from output\&.
+
+.TP
+\fB\-\-stream\fR
+Use streaming API \- useful when used in combination with \-\-relaxng or \-\-valid options for validation of files that are too large to be held in memory\&.
+
+.TP
+\fB\-\-chkregister\fR
+Turn on node registration\&. Useful for developeres testing libxml2 node tracking code\&.
+
+.TP
+\fB\-\-relaxng\fR \fIschema\fR
+Use RelaxNG file named \fIschema\fR for validation\&.
+
+.TP
+\fB\-\-schema\fR \fIschema\fR
+Use a W3C XML Schema file named \fIschema\fR for validation\&.
+
+.TP
+\fB\-\-nonet\fR
+Do not use the Internet to fetch DTD's or entities\&.
+
+.SH "SHELL"
+
+.PP
+ xmllint offers an interactive shell mode invoked with the \fB\-\-shell\fR command\&. Available commands in shell mode include:
+
+.TP
+\fBbase\fR
+display XML base of the node

+leave shell
+
+.TP
+\fBcat \fInode\fR\fR

+\fBcd \fIpath\fR\fR
+Change the current node to \fIpath\fR (if given and unique) or root if no argument given\&.
+
+.TP
+\fBdir \fIpath\fR\fR
+Dumps information about the node (namespace, attributes, content)\&.
+
+.TP
+\fBdu \fIpath\fR\fR

+Check the document for error\&.
+
+.TP
+\fBwrite \fIname\fR\fR
+Write the current node to the given filename\&.
+
+.SH "CATALOGS"
+
+.PP
+Catalog behavior can be changed by redirecting queries to the user's own set of catalogs\&. This can be done by setting the \fIXML_CATALOG_FILES\fR environment variable to a list of catalogs\&. An empty one should deactivate loading the default \fI/etc/xml/catalog\fR default catalog\&.
+
+.SH "DEBUGGING CATALOGS"
+
+.PP
+Setting the environment variable \fIXML_DEBUG_CATALOG\fR using the command \fB"export XML_DEBUG_CATALOG="\fR outputs debugging information related to catalog operations\&.
