Re: Regular expression help

I'm trying to replace all occurances of the X character in a text with Y, but only those X's that occur between bold tags (<b></b>).

<?php $str = 'This X and this X will not be fixed, but <b>this X and</b> and hopefully this <b>X</b> should be, along <b> with this X also. </b>, but not this X.'; function myreplace($match) { $from = 'X'; $to = 'Y'; return str_replace($from,$to,$match[0]); } $new_str = preg_replace_callback('#<b>.*</b>#Uis','myreplace',$str); echo $new_str; ?>
