I need the divs contents where the divs classes are red or green:
$s = '<div class="red">111</div> xxx <div class="green">222</div>';
preg_match_all('!<div class="(red|green)">(.*?)</div>!', $s, $tomb);
This works fine, but I don't need the first backreference, only the second, the div content. I tried with assertion:
preg_match_all('!<div class="(?=red|green)">(.*?)</div>!', $s, $tomb);
but it does not match anything.
How do I solve this problem?
