Garret, you said in your thread that I moved to GENERAL that you
feel your course left you ill equipped to solve your quizzes.
As far as regular expressions go there are a few very good on-line
tutorials 1) 2), and if you have some money to spare I'd recommend you
get O'Reilly's "Mastering regular expressions" by Jeffrey E.F. Friedl.
Cheers,
Tink
