Re: regex question

[Al <news@xxxxxxxxxxxxx>]

Murry's solution here is ideal since it only captures the single occurrence. 
Since I want to use it for a preg_replace(), it is perfect.

A couple of folks sent this pattern [^@]@[^@]; but, it doesn't work because I 
then have to remove the unwanted caracters on either side.

All it says is [not  @]@[not@] but, it captures the 2 characters on each side.

Murry's solution (?<!@)@(?!@) is good since it only captures the "@"

Thanks everyone....
