Thanks David for your quick help. Appreciate it. When I tried on python 2.7.3 the same thing you did below I got the error after matches.group(0) as follows:
AttributeError: NoneType object has no attribute 'group'. I tried to check 'None' for no match for re.search as the documentation says but it's not working. Unfortunately I cannot update the python version now to 2.7.13 as other programs are using this version and need to test all and it requires more testing. Any idea how I can fix this ? I am ok to use any other re method(not only tied to re.search) as long as it works.
