Regular Expression Resources Online

Where are they?

[Filipe]

Are there any detailed Regular Expression primers/tutorials online? The more extensive, the better. Also, it shouldn't be too difficult for beginners. Do any of these exist?

I've looked before, and if they're out there they certainly don't practice SEO. (Get your right-click ready, pop-ups galore!)

Ultraedit has a fair overview of RegExp in it's help files, I turn to that quite often.

[DrDoc]

Also, if you don't mind clicking around, you can always turn to the Perl or PHP manuals ;)
Extensive? Yes! :)

Offline, if you're learning perl try the Perl CD Bookshelf. It includes the Camel Book (Learning Perl) as well as the Perl Cookbook that has useful regex's.

A very good resource is O'Reilly's Mastering Regular Expression.

You'll have to pay for them, but like all O'Reilly books (is there a useless O'Reilly book??) they're worth their weight in gold...
