Hi Steve,

I don't think that the dialog returns anything but the complete filename. So assuming that you get the complete filename, i.e. 'myfilename.xml', you could just split the name at the '.' to get the extension. 

>>> filename = 'myfilename.xml'
>>> extension = filename.split('.')[-1]
>>> extension
'xml'

Regards
Jorgen
