I wrote an article on informIT.com about how to use them. It includes 
a few simple examples but nothing super complex. (Its basicaly 
the RE chapter in my book without the case study).

There's also a python program available somewhere that allows you 
to type in REs and test them. I think I have a copy somewhere if 
you need to I can probably dig it out....

Its called recon.py, heres the header:
#!/usr/bin/env python
# Regular expression test console
# By Brent Burley, 2001, erburley@ix.netcom.com
# This software is placed into the public domain

It's 15K long.

The O'Reilly book is the vbest place to go, the definitive 
guide to REs IMHO. Lots of real world examples including a massive 
one to test for a canonical RFC822 compliant email address!
