Expat is a stream-oriented XML 1.0 parser library, written in C, more precisely C99. As one of the first available open-source XML parsers, Expat has found a place in many open-source projects. Such projects include the Apache HTTP Server, Mozilla, Perl, Python and PHP. It is also bound in many other languages.
