Hello all

i started learning regex yesterday as part of my revision, and am surprised how quickly i picked up the basics

this is my attempt at an email validation (i saw the RFC822 full page jobby and was in awe)

Code:
 ^[A-Za-z]+[\w\-\.]*\@[a-zA-Z]*\.([a-z]{2,4}| [a-z]{2}\.[a-z]{2})+$


and am struggling with the last co.uk bit can anybody see what it missing

also any hints and tips to make me a better REGEX'er

Thanks for your help
Jon

As for an explanation rather than just a link that doesn't help the actual question,
Code:
([a-z]{2,4}| [a-z]{2}\.[a-z]{2})+$

There's a space in there that shouldn't be.

Perhaps it doesn't help the actual question, but it is an excellent article. Note that the OP also asked for general hints and tip to become better at regex: that website is one of the better on-line sources there are.
