Question

I would like to use DOMDocument or another proposed method to do the following in wordpess:

I have this html saved in a variable:

<div id="gallery-3232" class="gallery gallery-3232">
<li><a href=""><img src="" alt="" /></li>
<li><a href=""><img src="" alt="" /></li>
<li><a href=""><img src="" alt="" /></li>
<li><a href=""><img src="" alt="" /></li>
</div>

And I would like to end up with a variable containing that:

<li><a href=""><img src="" alt="" /></li>
<li><a href=""><img src="" alt="" /></li>
<li><a href=""><img src="" alt="" /></li>
<li><a href=""><img src="" alt="" /></li>

How can I do this but without javascript. With the use of PHP.

$source = '<div id="gallery-3232" class="gallery gallery-3232">
            <li><a href=""><img src="" alt="" /></li>
            <li><a href=""><img src="" alt="" /></li>
            <li><a href=""><img src="" alt="" /></li>
            <li><a href=""><img src="" alt="" /></li>
            </div>';

$list = new DOMDocument();
$list->loadHTML($source);

$listItems = $list->getElementsByTagName('li');

$listString = "";

foreach ($listItems as $list) {
    $listString .= $list->C14N();
}

echo $listString;
