Any reason why cStringIO in 2.5 behaves different from 2.4?

This isn't some sophisticated XML tool that tells me the string
is wrong. It's a changed behavior of cStringIO that throws an
exception. While I'm just using the method parseString() of
xml.sax.

We both repeat ourselves. I don't think this thread brings
something new.


I'm all for correct XML and hate XML bozos. But there are limits
