  // PHP's \DOMDocument serialization adds extra whitespace when the markup
  // of the wrapping document contains newlines, so ensure we remove all
  // newlines before injecting the actual HTML body to be processed.
  $document = strtr($document, array("\n" => '', '!html' => $html));

  $dom = new \DOMDocument();
  // Ignore warnings during HTML soup loading.
  @$dom->loadHTML($document);
