Should be ET.parse(os.path.join(watch_dir, f)) I think...

The glob module can filter file names based on patterns.
os.path.isfile() will tell you if something is a file. So for example:

pattern = os.path.join(watch_dir, "*.xml")
for f in glob.glob(pattern):
  if not os.path.isfile(f): #already did the join in the pattern
  tree = ET.parse(f)

Jason Orendorff's path module is useful for this also though the doc
site seems to be down:
