I use regular expressions for that kind of thing. Here's an example; look up the regex docs on the Netscape Developer Connection or any other good Javascript source.

"2-3-2004".match(/(\d{1,2})-(\d{1,2})-(\d{4})/)

The returns an array (if the match occurs):

2-3-2004, 2, 3, 2004

Otherwise it returns null.
