<p>Libxml is the XML C library developed 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 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>
|
|
<p>In most cases libxml 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> :
|

libxml implements a basic FTP client code</li>
