Convert SimpleXML to DOMDocument, not DOMElement

Question

I need to convert a SimpleXML object to a SimpleXML in DOMDocument to use it with DOMXPath . I need DOMXPath so that I can use its registerPHPFunctions method. It can be done?

With dom_import_simplexml I get a DOMElement , not a DOMDocument .

Answer 1

You can extract a document from $ anyDOMNode-> ownerDocument

Answer 2

 $dom=new DOMDocument; $dom->loadXML($sxml->asXML());
