So here is a script that'll just loop through each letter of a string and uppercase the letters that are within the tags but not within quotes (single or double). Adapt to your needs. <?php $str = 'This is <img src=\'foo.jpg\' width="50" height="40" bad> a <b>thing</b>, okay? <a href="foo.html">Link</a> But 4 > 2 and 4 <= 4, okay? <yeah>'; $length = strlen($str); $within_quotes = 0; $within_tag = 0; for($x=0;$x<$length;$x++) { if(!$within_tag) { if($str{$x} == '<' && preg_match('![/a-zA-Z]!',$str{$x+1})) { $within_tag = 1; $within_quotes = 0; } } elseif($within_tag) { if($str{$x} == '"' || $str{$x} == "'") { $within_quotes = !$within_quotes; } elseif($str{$x} == '>' && !$within_quotes) { $within_tag = 0; } } if($within_tag && !$within_quotes) { $str{$x} = strtoupper($str{$x}); } } echo "<pre>",htmlentities($str),"</pre>"; ?> ---John W.
