DOMXPath - How to wrap an element in a HTML tag?

Question

I want to warp an <img> element in a <p style="text-align:center"></p> . This is the code I have so far:

$dom_err = libxml_use_internal_errors(true);
$dom = new \DOMDocument('1.0', 'utf-8');
$dom->loadHtml(mb_convert_encoding($arr['nm_corpo_artigo'], 'HTML-ENTITIES', 'UTF-8'));
$xpath = new \DOMXPath($dom);
foreach ($xpath->query("//figure/img") as $img) {
    $img->setAttribute('style','max-width: 100%; height: auto;');
    $img->setAttribute('class','mb-4 mt-4');
}
$body = $dom->saveHTML();

And this is the structure genrated by the code:

At the end Iwould like to have:

<figure ...>
   <p style="text-align:center"><img ...><figcaption>...</p>
</figure ...>

...

What you need to do is create a new paragraph element (with the new attribute) and replace the image tag with this new tag and then add the img tag back into the new paragraph tag...

foreach ($xpath->query("//figure/img") as $img) {
    $img->setAttribute('style','max-width: 100%; height: auto;');
    $img->setAttribute('class','mb-4 mt-4');
    $p = $dom->createElement("p");
    $p->setAttribute('style', 'text-align:center');
    $img->parentNode->replaceChild($p, $img);
    $p->appendChild($img);
}
