Regular Expression - using the ?:

Okay so it's not quite the bees knees of reg exp, but I want to replace the text ' action="./somedir/somepage.xxx">' where the double quotes may or may not be there, as might the > as the end. But I don't want the > at the end matched. $replace = ' action="http://www.myserver.com.au/mypage.php3" '; $text = preg_replace('|\s+action\s*=\s*.*?(?:[>\s])+|i', "$replace" , $in_text)); echo "$text"; It seems to match for most things, except when $in_text is action=/page.asp> It still matches the >, but shouldn't the ?: not include the matched > in the text to replace ? Can someone else try this in a script or tell me if it's a 'special' feature of php. Thanks, Nick
