This document describes libxml, the XML C parser and toolkit developed for the Gnome project. XML is a standard for building tag-based structured documents/data. Here are some key points about libxml:

- Libxml2 exports Push (progressive) and Pull (blocking) type parser interfaces for both XML and HTML.
- Libxml2 can do DTD validation at parse time, using a parsed document instance, or with an arbitrary DTD.
- Libxml2 includes complete XPath, XPointer and XInclude implementations.
- It is written in plain C, making as few assumptions as possible, and sticking closely to ANSI C/POSIX for easy embedding. Works on Linux/Unix/Windows, ported to a number of other platforms.
- Basic support for HTTP and FTP client allowing applications to fetch remote resources.
- The design is modular, most of the extensions can be compiled out.
- The internal document representation is as close as possible to the DOM interfaces.
- Libxml2 also has a SAX like interface; the interface is designed to be compatible with Expat.
- This library is released under the MIT License. See the Copyright file in the distribution for the precise wording.

Warning: unless you are forced to because your application links with a Gnome-1.X library requiring it, Do Not Use libxml1, use libxml2
