I'm an XML newbie myself, so there's NO WARRANTY whatsoever.

As from what I read from the xmllib docs you have to derive a class
along the following lines:

class MY_XML_PARSER(xmllib.XMLParser):

    attributes = {
                   'SOME_TAG' : { 'ATTR' : 'DEFAULT_VALUE',
                                  'NODFLT' : None,
                                },
                 } 

    elements = { 
                  # Docs say 'function' try with bound method first
                  # if you get a wrong argument count error, drop
                  # "self.". If the latter succeeds, report documentation
                  # bug after crosschecking newest version of docs

                  'SOME_TAG' : (self.start_SOME_TAG, self.end_SOME_TAG),

                  # repeat for other tags
               }

    def start_SOME_TAG(self, attr_dict):
        """document start_SOME_TAG here"""
        # do sth usefull
	pass # just to be syntactically correct :)

    def end_SOME_TAG(self):
        """document end_SOME_TAG here"""
        # do sth usefull
	pass # just to be syntactically correct :)

Note: this is completely untested, but hopefully isn't completely
wrong :)
