Determine what element is now xpath html foreach?

Question

I am in the middle of a process that should extract something from a HTML page. I am fairly new to DomDocument in PHP, but I got this together from some tutorials and Stack Overflow.

Unfortunately, I need to know what element I am currently getting in the foreach loop below. As far as I know, the getName() function has something to do with XML, because it gives an Undefined Function Fatal error. Do you guys know any way to do this?

$rawdom = new DOMDocument();
$rawdom->loadHTML($page);

$finder = new DomXPath($rawdom);
$nodes = $finder->query("//dl[contains(@class, 'layout__definitionlist')]");

$tmp_dom = new DOMDocument(); 
foreach ($nodes as $node) {
    echo $node->getName();
    $tmp_dom->appendChild($tmp_dom->importNode($node,true));
}
$innerHTML = $tmp_dom->saveHTML();

echo $innerHTML;

Answer 1

With DOMElement objects, the element name is not accessible using a getName() function, but as property $tagName:

echo $node->tagName;

getName() is only available with SimpleXMLElement, which is another XML/XPath API for PHP.
