将SimpleXML转换为DOMDocument，而不是DOMElement

Question

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

With dom_import_simplexml I get a DOMElement , not DOMDocument .

Answer 1

您可以从$ anyDOMNode-> ownerDocument中获取文档

Answer 2

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