getting several elements by tag name and checking elements tag in a loop echoing it

Question

This is code sample that works

$doc->loadHTML($article_header);
$imgs = $doc->getElementsByTagName('img');
foreach ($imgs as $img) {

$imgs takes from $doc elements with tag name img and then I do some operations.

Now I want to getElementsByTagName > img OR iframe and then using $img check which element is this and echo if it is iframe or img.

Please modify my code if it is possible.

You can use XPath on your DOMDocument as follows:

$doc->loadHTML($article_header);
$xpath = new DOMXpath($doc);

$imagesAndIframes = $xpath->query('//img | //iframe');

$length = $imagesAndIframes->length;
for ($i = 0; $i < $length; $i++) {
    $element = $imagesAndIframes->item($i);

    if ($element->tagName == 'img') {
        echo 'img';
    } else {
        echo 'iframe';
    }
}
