This document describes libxml, the XMLC parser and toolkit developed for theGnomeproject. XML is a standardfor buildingtag-basedstructured documents/data. Here are some key points about libxml: Libxml2 exports Push (progressive) and Pull (blocking) typeparserinterfaces for both XML and HTML. Libxml2 can do DTD validation at parse time, using a parseddocumentinstance, or with an arbitrary DTD. Libxml2 includes complete XPath, XPointerand XIncludeimplementations. It is written in plain C, making as few assumptions as possible,andsticking closely to ANSI C/POSIX for easy embedding. WorksonLinux/Unix/Windows, ported to a number of other platforms. Basic support for HTTP and FTP client allowing applications tofetchremote resources. The design is modular, most of the extensions can be compiled out. The internal document representation is as close as possible to the DOMinterfaces. Libxml2 also has a SAX like interface;theinterface is designed to be compatible with Expat. This library is released under the MITLicense.See the Copyright file in the distribution for the precisewording. Warning: unless you are forced to because your application links withaGnome-1.X library requiring it, Do Not Use libxml1,uselibxml2 Daniel Veillard
