I believe that there have been a few changes to the organization of
the SAX modules and the interfaces of the classes themselves.
Attached is a simple SAX example that should help get you started,
if you haven't already groped your way through it.
Also, you will want to read the following and the pages it links
to:
http://docs.python.org/lib/module-xml.sax.html
http://docs.python.org/lib/module-xml.sax.xmlreader.html
http://docs.python.org/lib/module-xml.sax.handler.html
Etc.
