Regular expression help required

Evil Phil

This is for an Asp.net (2) regex validator control. Its the default pattern matcher for a valid email address.

\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*

How can I modify this to ignore trailing whitespace in the email address being validated?

Been a while but I think this will do it:

\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*[¬\s]

Hope that helps

What I ended up doing in the end was \w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*\s*

which ingnores any white space that may be there, including tabs.

\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*[¬\s]

Only seems to work if there is a single nonbreaking space present..

I found a suggestion in the Perl FAQ. It includes a link to a script that does a complete check (including contacting the email server). I'm sure both could be ported to ASP.

Thanks daymobrew but its just for a form processing. It doesn't have to be an existing email address, just as long as its resembles one.
