"Some people, when confronted with a problem, think 'I know, I'll use XML.' Now they have two problems."

Downvoting? This is actually the quote I heard, though I know regexp'es are older than XML (and a good deal more useful, if you ask me).

I find this quote funny, but untrue. If you use regular expressions for the right problems, you solve the problem. If you use it for the wrong problems, well, then regular expressions aren't where you should put the blame.
