Looking for decent regular expressions guide online.

hello,

I'd like to ask if there is someone here who could point me to decent guide about regular expressions. As for now I'm learning mostly from http://www.regularexpressions.info/ but I'd like something which would be more exercise book than reference manual.
anyone with idea where to go?

cheers,
Arin.

Wikipedia have a short introduction to regular expressions. That page also have very good external links to examples and tutorials. http://en.wikipedia.org/wiki/Regular_expression

 

This is one of my favoritist references:

I also recommend you to try this software: http://weitz.de/regex-coach/. It's very helpful and free to download.
I use it all the time and helps me a lot.
