使用xpath查找并将其从父项中删除：

// Build a new DOMDocument, load it up with your HTML
$doc = new DOMDocument();
$doc->loadHTML($html);

// Reference to our DIV container
$container = $doc->getElementsByTagName("div")->item(0);

// New instance of XPath class based on $doc
$xpath = new DOMXPath($doc);

// Get images that contain 'specific-domain.tld' in their src attribute
$images = $xpath->query("//img[contains(@src,'specific-domain.tld')]");

// For every image found
foreach ($images as $image) {
    // Remove that image from its parent
    $image->parentNode->removeChild($image);
}

// Output the resulting HTML of our container
echo $doc->saveHTML($container);
