如何回显DOMNodeList对象和DOMElement对象？

Question

I am using a loop to populate an array called $list. it is working like a charm..

// $content is a DOMNodeList Object  
// $value is a DOMElement Object 

$list = array();

foreach ($content as $value){

    array_push($list, 'title'=>$value->nodeValue);  

}

Eventhough my loop is populating my array correctly, I would like to digg into that DOM thing a little more to understand things better (this DOM thing is to new to me...). So what I would like, is to see how the DOMNodeList Object ($content) and DOMElement Object ($value) looks like.

So my question is simple: how can I "echo-out" those 'elements'?

Answer 1

Better than "echo-out" DomElement, read the documentation: http://php.net/manual/en/class.domelement.php.

If you want to see XML representation, use http://www.php.net/manual/en/domnode.c14n.php, i.e.

echo $value->c14N(false,true);
