I wouldn't recommend this approach, since regexes are fidgety to write and worse to read (believe me, I've seen millions). They're easy to get wrong, and engines may differ in subtle but important ways. The fact that the top ten regexes contains at least one such subtle bug should suggest that regexes are, in fact, not a good tool for input validation.
