Stephen ,

Further clue - I may or may not be helping. I have the XML extensions 
installed, which is why my "xml.sax.saxlib" is in "_xmlplus.sax" (in the 
"site-packages" folder).

In Lib\xml\__init__.py is the following magic :

try:
    import _xmlplus
except ImportError:
    pass
else:
    try:
        v = _xmlplus.version_info
    except AttributeError:
        # _xmlplue is too old; ignore it
        pass
    else:
        if v >= _MINIMUM_XMLPLUS_VERSION:
            import sys
            sys.modules[__name__] = _xmlplus
        else:
            del v

This bit  ``sys.modules[__name__] = _xmlplus`` tells python to use the 
XML extension as the XML module instead of the default one.

However - there is also some nice(!) magic going on in 
"Lib\xml\sax\__init__.py"

    def _create_parser(parser_name):
        drv_module = __import__(parser_name,{},{},['create_parser'])
        return drv_module.create_parser()

This is creating parsers and inserting them into the "xml.sax" 
namespace. I have disgnosed the problem... but not suggested a solution !

Hopefully someone else can see clearly...
