XPath search under given element

Question

The only way I know in PHP to execute an XPath query in a DOM, DOMXPath , works only with DOMDocument :

 public __construct ( DOMDocument $doc ) 

Is there a similar search mechanism for DOMElement ?

The problem is that I need to look for abritrary XPath (which I do not control) regarding DOMElement .

I've tried:

 $domElement->getNodePath() . '/' . $xPath; 

But if XPath contains | (or symbol), this approach does not work.

Yes there is. The element is also part of the document, so you use the xpath object of the document, but when you run the request, there is a second parameter, which is the context node, to which the request in the first parameter refers to

 // query all child-nodes of $domElement $result = $xpath->query('./*', $domElement); 

See DOMXpath::query() .
