hlaford Bipolar (III) Inmate From: USA! USA! USA! Insane since: Oct 2001	posted 06-14-2002 22:06 I found a couple links that I've been using (from Google). I've been hoping for a single regex to handle email formats (including quoted strings and IP addresses). Up until now, I've been using a simpler regex which included only the basics (handling 99.99% of addresses we've dealt with). http://www.cs.tut.fi/~jkorpela/rfc/822addr.html http://www.w3.org/Protocols/rfc822/rfc822.txt

Slime Lunatic (VI) Mad Scientist From: Massachusetts, USA Insane since: Mar 2000	posted 06-14-2002 23:38 There's some O'Reilly book that has a regular expression matching every email format... I think it's either Mastering Regular Expressions or the Perl Cookbook... I forget though. Hold on, let me check if my perl book has it... Ah, my CGI Programming with Perl book says that you can find it in Mastering Regular Expressions, but it fits a really old standard (RFC 822) which is, in fact, still standard, but it matches some weird things. It's correct though. Anyway, you might take a look at that.

My guess is that JavaScript won't support the full 6,598-byte regex since it lacks the look-aheads. Maybe we'll just plug in the pieces we need when we need them. I'm fairly certain we can use it in server-side code--even in VB, believe it or not.
