One way that I learn this type of subject (regex) is to tackle lots of small regex quizzes starting from easy stuff and building on that to become more complex. Does anybody know of any web site that provides "solve this with regex" problems and then provides some solutions to each problem?

 Thanks.
 

This one.  Follow the Construction Advice forum posts and watch what works for the questions asked, likely there's no other regex pattern construction forum that sees more traffic.

I would also recommend you read Friedl's "Mastering Regular Expressions" as it's the definitive text for regex.

I second  both of ddrudik's recommendations. Especially Friedl's "Mastering Regular Expressions": it's a must have for sure!

Edit: oops, didn't realise this thread is rather old...

try using the software Regex Buddy....
