Hi All, I am trying to identify an email address in a page but I don't want to return the email if it's webmaster@xxxxxxxxxxxxx Here's what I have; (\w[-._\w]*\w(?<!webmaster)@\w[-._\w]*\w\.\w{2,3}) It returns nothing, however when I take out the lookbehind section; (\w[-._\w]*\w@\w[-._\w]*\w\.\w{2,3}) it works fine, returning all email addresses in a page. What is wrong with my syntax? alex hogan -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
