Regex / DOMDocument - match and replace text not in a link

Question

I need to find and replace all text matches in a case insensitive way, unless the text is within an anchor tag - for example:

Match this text and re         


        

Answer 1

<?php
$a = '<p>Match this text and replace it</p>
<p>Don\'t <a href="/">match this text</a></p>
<p>We still need to match this text and replace it</p>
';
$res = preg_replace("#[^<a.*>]match this text#",'replacement',$a);
echo $res;
?>

This way works. Hope you want realy case sensitive, so match with small letter.
