Expat is an XML parser library written in C. It is a stream-oriented parser in which an application registers handlers for things the parser might find in the XML document (like start tags). An introductory article on using expat is available on xml.com.
This project aims to maintain Expat for both current and future users while improving the API to allow more reliable and robust access from "scripting" languages such as Python and Perl. We invite the community to participate on the mailing lists to help shape the future of Expat.
