PHP DomDocument: how to process all links on a page?

Question

PHP

Hello!
Can you please tell me how to process all links on the page (for example, add the “foo” class to them), and return them to their places in the text?

<?php
$content = <<<EOD
<p>Lorem <a href="#">ipsum</a> dolor sit amet, consectetur adipisicing elit. Explicabo porro illum nesciunt. <a href="#">Voluptatem</a>, blanditiis esse, quod <a href="#">expedita</a> repellendus consequuntur dolore pariatur dicta tempora facere sint labore at magnam, rem assumenda.</p>

<p>Commodi, expedita? <a href="#">Accusantium reiciendis</a> in voluptatem veniam ullam! Et, porro architecto in dicta maxime blanditiis iusto, totam quis rerum voluptas numquam vero doloremque! Itaque impedit eligendi dignissimos, et <a href="#">veritatis eius</a>.</p>
EOD;

$dom = new DOMDocument('1.0', 'UTF-8');
$dom->loadHTML($content);
$xpath = new DOMXPath($dom);

$links = $xpath->query('//a');

foreach($links as $link) {}

I understand how to get the links themselves. I don’t understand how to return them to their places after processing (how to get the text with processed links)?
Thank you!
