What SAX Is Not
SAX by itself is just an API, and a number of implementations are
available from many of the familiar sources. The most commonly used parsers are
Xerces from the Apache XML project and Java API for XML Processing (JAXP) from
Sun Microsystems. A good list of parsers can be found at http://www.xmlsoftware.com.
SAX was originally developed in Java, but similar implementations are
available in other languages as well. There are implementations for Perl,
Python, and C++, for example. You can find more information at http://www.megginson.com/SAX/applications.html.
