You shouldn't be asking questions about using Python on python-dev -- this list is for development of Python.

Your problem is easily explained however: the second argument to p.findall() should be an offset, not a flag set. (You are confusing re.findall() and p.findall().)

Any wrong with the script? I tried Python2.4/2.6/2.7, the result is same. Thank you. Hongchao Lu
