I have the following pattern which I'm trying to use to match credit card expiration dates:
(0[1-9]|1[0-2])\/?(([0-9]{4})|[0-9]{2}$)
and I'm testing on the following strings:
02/13
0213
022013
02/2013
02/203
02/2
02/20322
It should only match the first four strings, and the last 3 should not be a match as they are invalid. However the current pattern is also matching the last string. What am I doing wrong?
