用class删除div并保留所有其他html

Question

My html content:

$content = <div class="class-name some-other-class">
<p>ack</p>
</div>

Goal: Remove div with class="class-name so that I'm left with:

<p>ack</p>

I know strip_tags($content, '<p>'); would do the job in this instance but I want to be able to target the divs with a certain class and preserve other divs etc.

And I'm aware that you shouldn't pass html through regex - So whats the best way/proper way to achieving this.

Answer 1

$doc = new DOMDocument();
libxml_use_internal_errors(true);
$doc->loadHTML($content); // loads your HTML
$xpath = new DOMXPath($doc);
// returns a list of all links with class containing class-name
$nlist = $xpath->query("div[contains(@class, 'class-name')]");

// Remove the nodes from the xpath query
foreach($nlist as $node) {
   $node->parentNode->removeChild($node);
}

echo $doc->saveHtml();
