Help With Regex and Yahoo Pipes...Please Help!

[hellohellosharp]

Okay, I need a Regex that will match everything except email addresses....

So far I am using this Regex that matches email addresses.

\b[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}\b

It does its job perfectly, but like I said, I need the opposite...

Can anyone help me with this?

Sorry I realize this isn't exactly PHP but I wasnt sure what forum to put it in

Thanks guys
