When dealing with XML provided by a user, it is nice to be able to provide targeted error messages.
This small library provides 3 functions: xml_parse_file, xml_parse_string and xml_error_str.
To use it simply call xml_parse_file in places you would otherwise call xml.minidom.parse, and xml_parse_string in place of xml.minidom.parseString.
When you want to report an error to the user call xml_error_str passing element that is problematic.
Checkout test.py for some usage examples.
Feel free to take pyxmlerrors.py and simply drop it in to your project.
