如何回显一个DOMNodeList对象和一个DOMElement对象？

问题描述

我正在使用循环来填充一个名为$ list的数组。它的工作就像一个魅力。

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);

}

事件我的循环正好填充我的数组，我想去挖掘这个DOM的东西多一点，以了解更好的东西（这个DOM的东西是给我新的...）。所以我想要的是看看如何在$ code> DOMNodeList Object（$ content）和 DOMElement Object（$ value）看起来像。

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.

所以我的问题很简单：我如何回声那些元素？

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

推荐答案

比echo-outDomElement更好，阅读文档：。

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

如果要查看XML表示，请使用，
ie

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

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