Thanks for the report. What do you mean with 'the wrong,
"xml.parsers.expat"'? There really is an exception
xml.parsers.expat.error, and it really is raised from
xml.parsers.expat (aka pyexpat).
It turns out that it is only raised for Parse, not for ParseFile,
which is a bug introduced when the return value of these functions was
changed from a number to an exception. In the PyXML CVS, I have
corrected that error. As a result, PyXML 0.6.2 will build its own
pyexpat.c even for Python 2.0, which will implement the documentation.
