in thread Suggestion for regular expression speed improvement.
You need to think out of the box. Make your system handle the various cases. A regex, a split, an unpack, maybe even an xml parser....
Definitely doing it the way you are is wrong. If you are really insistent on ignoring our advice (unwise really), then at least use inversion and you might want to investigate the (?>...) construct "atomic matching". As well as adding anchors to your pattern.
