Yes,this is a regex for email matching,but may be broken under some cases. The username part can be all a-z,A-Z,0-9, "-", "." and "_" characters. The first tld part (before the ".") take the same character range as username. the last tld part (after the ".") can be a-z and A-Z only,and the length is from 2 to 5.
In fact this is not an exact regex for email address,b/c it also match the cases below: [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] and even, [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] There is an article on internet "How to Find or Validate an Email Address". I didn't check it carefully,but just a reference for you. http://www.regular-expressions.info/email.html On 10/24/07, newBee <[EMAIL PROTECTED]> wrote: > ^([a-zA-Z0-9_\-\.]+)@([a-zA-Z0-9_\-\.]+)\.([a-zA-Z]{2,5})$ > > Its look like an email address... is it..? it will be a great help if > some one could give a breakdown on the this regex. > > thanks in advance... > > > -- > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] > http://learn.perl.org/ > > > -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] http://learn.perl.org/
