<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, ...)</p>
<p>Libxml2 implements a number of existing standards related to markup
languages:</p>
<ul><li>the XML standard: <a href="http://www.w3.org/TR/REC-xml">http://www.w3.org/TR/REC-xml</a></li>

<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>
