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.

Thabnk you

  1. $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;

  2. I just tested this, I think it’s what you require. Basically load the HTML into a DOMDocument, get the element you need by ID and then iterate through its child nodes and output:

    $html = '<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>
';

$doc = new DomDocument();
$doc->loadHtml($html);
$div = $doc->getElementById('gallery-3232');
$output = '';
foreach($div->childNodes as $element)
{
    $output .= $element->ownerDocument->saveHtml($element);
}
echo $output;

  3. Here’s a quick and dirty way using a regex:

    $string = preg_replace('~</?div[^>]*>~', '', $string);

    Note: like I said, this is a quick and dirty way. If you’re sure of your input – use this. However, if you are filtering uncertain input, you’d be better off parsing it properly.
