This does what you want to $html, but it doesn't do it in a single
regex. I'm not sure it can be done with a single regex, and if it can, I
doubt it's simple. I don't feel like investigating too far :)
Cheers,

Considering you marked the email as urgent, perhaps you have better
things to do than try to squeeze your problem into a regex. Feel free to
post your single regex when you find it... a side note of how much time
you wasted would be most informative too.
Cheers,
Rob.

Rob, $reps = array ( array ( 'match' = '#a.*/a#Uims', Can you explain what the 'U' from #Uims does? Does it have to do with Unicode? I can't find it anywhere (preg_match doc, man perlre, man perlop).

I can't find it anywhere (preg_match doc, man perlre, man perlop). It makes the match Ungreedy. Look at the following example: $text = a href=blah/a ... a href=bleh/a; If we match with the following: preg_match_all( '#a.*/a#Uims', $html, $matches ) Then $matches will contain 2 matches... 1. a href=blah/a 2. a href=bleh/a However if we match with the following: preg_match_all( '#a.*/a#ims', $html, $matches ) Then $matches will only get 1 match... 1. a href=blah/a ... a href=bleh/a This is because the default behaviour is greedy, it will match as much as possible even if a shorter match exists.
