Get all img tags and add <a href=""/> between

Question

I want to get all img tags from drupal site and then add a tag between.

I try the below:

 $html_img = new simple_html_dom();
  // Load HTML from a string.
 $html_img->load($node->body[LANGUAGE_NONE][0]['value']);
  // Remove all plain text fragments.
  foreach ($html_img->find('img') as $e ) {
    $e = "<a href='$node_url'>$e</a>";
  }

With above code I take all img tags from drupal but the $e = "<a href='$node_url'>$e</a>"; doesn't put a link to img tags.

Answer 1

$dom = new DOMDocument;
$dom->loadXML($xml);
$images = $dom->getElementsByTagName('img');
foreach ($images as $img) {
    echo "<a href='#'>$img</a>";
}

DomDocument.

Was the first result in Google.
