As well as the documentation referenced above, I have found a tool called My REGEX Tester very good for checking out and experimenting with REGEX.I have a link to it in Found new online Regex tool.Plus there is a nice website called Regular-Expressions Quickstart. This teaches all of the basics of REGEX.
REGEX can be very useful, and easy to use if you just study up on some of the basics.
