[Pywikipedia-l] XMLreader.py

[Dmitry Chichkov]

As far as I remember xmlreader can use alternative mechanisms of XML
parsing: cElementTree, ElementTree, regexp. The version of the cElementTree
depends on the Python version. My bet it is a regexp method fault. Or maybe
cElementTree fault [IMHO this library have never been up to the standard].
