Have you checked what kind of object temp is?

If your search fails it returns None. none does not have a group()
attribute, 
hence the error.

You need to either handle the exception (the Pythonic solution) or test to 
see if its not None:

if temp != None: 
    res = temp.group()

Thats my guess! :-)
