Hi there

Had an odd error trying to run a utility called SVGMath:

File "/home/jason/downloads/SVGMath-0.3.1/svgmath/mathconfig.py", line 54, in startElement
    elif u"afm" in attributes:
  File "/usr/lib/python2.5/site-packages/_xmlplus/sax/xmlreader.py", line 316, in __getitem__
    return self._attrs[name]
KeyError: 0


It appears that AttributesImpl in the sax package (xmlreader.py) doesn't implement __contains__, so the 'in' operator throws an error.  This is on Kubuntu/Linux, so I'm not sure if it's distro-specific or all Linux versions of Python.

In any case, if you add:

    def __contains__(self, name):
        return self._attrs.has_key(name)

to AttributesImpl in xmlreader.py (as per the Windows version of Python), the problem goes away.

Kind regards
Jason

It looks like the xmlreader.py doesn't come from the Python distribution, but from the PyXML library, which is maintained elsewhere.

Reported in the PyXML tracker.
