Error is :

#!/usr/bin/env python
module load python/core/2.5
+ module load python/core/2.5
from xml.parsers.xmlproc import xmlval

You have libraries and commands already doing the same.

You could use them.

try xmllint command - it checks for XML well formedness

Or is your question on how to reinvent that so that you could learn how is it actually done ?
