   It seems you are trying to do the following - match or search for
regular expression:

match_object = re.search(pattern, string)
groups = match_object.groups()

   But your regexp didn't match anything in the string, so match_object
here is really None. Test it before doing anything with it:

match_object = re.search(pattern, string)
if match_object:
   groups = match_object.groups()
else:
   print "No match!"
