Question

I am trying to replace content inside particular div tags (id=”dd-header”) with a comment. Tried several methods, and regular expressions. This is my latest try:

$html = preg_replace('/(<div\sid=\"dd\-header\">)[^<]+(<\/div>)/i', '<!-- Comment -->', $html);

Couldn’t get it working. What am I doing wrong here?

NOTE: div tags further have multiple tags

Sample Code to Replace

<div id="dd-header">
    <a id="logo-small" href="/" title="title"></a>
    <a href="http://url/">Link 1</a> | 
    <a href="javascript: (function () {window.location = 'http://url=' + encodeURIComponent(window.location.href);})()">Link 2</a>
    <!-- <a href="http://url">Image</a> | -->
    | <a href="url">Link 3</a></div>

Answer 1

$html = preg_replace('/(<div\sid="dd-header">)([^<]|<.+>.*<\/.+>)+(<\/div>)/i', '$1<!-- Comment -->$3', $html);
