<p>Libxml is the XML C library developped for the Gnome project. 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 bracket. HTML is the most well-known
markup language.</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>
<li>Namespaces in XML: <a href="http://www.w3.org/TR/REC-xml-names/">http://www.w3.org/TR/REC-xml-names/</a>

</li>
</ul>
<p>In most cases libxml tries to implement the specifications in a relatively
strict way. To some extent libxml2 provide some support for the following
other specification but don't claim to implement them:</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 in top of
libxml2</li>
<li>
<a href="http://www.cis.ohio-state.edu/rfc/rfc959.txt">RFC 959</a>
: libxml 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>Libxml2 is known to be very portable, should build and work without
serious troubles on a variety of systems (Linux, Unix, Windows, CygWin,
MacOs, MacOsX, RISC Os, OS/2, VMS, QNX, MVS, ...)</p>

libxml2</li>
