It's an iterator, so compose it with a filter.  Here's one
NOTE: untested!


from __future__ import generators

import fnmatch

def xfnmatchs(filenames, pattern):
   for filenames in filenames:
     if fnmatch(x, pattern):
       yield filename


and you could use this like

   for filename in xfnmatches(xlistdir("/etc"), "*.txt")):
     if filename.find("spam") != -1:
       break
