It's not a matter of escaping. You're matching too much with the ".*". If you're sure you won't have any right-point-brackets inside comments, you can use something like: $text = ereg_replace("<!--[^>]*-->","",$text); Accurately matching comments in an extended regular expression is tricky though. The only thing you can really *negate* in an ereg is a range, not an atom. And the close of the comment can't be prepresented as a range, since it's multiple characters. Not to say it can't be done. I just can't think of how at the moment. :) -- Paul Chvostek <paul@it.ca> it.canada http://www.it.ca/ Free PHP web hosting! http://www.it.ca/web/
