PHP XMLReader获取父节点？

Question

While parsing an XML File using the XMLReader Method, how do I get the parent node of an element ?

$xml = new XMLReader();
$xml->XML($xmlString);
while($xml->read())
{

$xml->localName; // gives tag name
$xml->value; // gives tag value

// how do I access the parent of this element 
}

I think you want: XMLReader::moveToElement
