I have an idea: use a regular expression :D
Unfortunately, I don't have the knowledge of these down well enough to 
just spout one off OTOH,
and I've got somewhere I have to be, but I believe that you could use 
regexps to solve this quite easily.
Good luck, and hopefully someone more helpful will chime in.
