如何从DOMXPath :: query()方法获取完整的HTML? [英] How to get full HTML from DOMXPath::query() method?

问题描述

我有一个文档，要从中提取未删除内容的特定div. 我这样做:

I have document from which I want to extract specific div with it's untouched content. I do:

$dom = new DOMDocument();
$dom->loadHTML($string);//that's HTML of my document, string

和xpath查询:

$xpath = new DOMXPath($dom);
$xpath_resultset =  $xpath->query("//div[@class='text']");
/*I'm after div class="text"*/

现在我对$xpath_resultset

$my_content = $xpath_resultset->item(0);

我得到的是对象(不是字符串)$ my_content，可以回显或将settype()字符串，但是结果是完全剥离的标记?

what I get is object (not string) $my_content which I can echo or settype() to string, but as result I get is with fully stripped markup?

如何在这里从div class ='text'中获得所有?

What to do to get all from div class='text' here?

推荐答案

只需将节点传递到 DOMDocument::saveHTML 方法:

Just pass the node to the DOMDocument::saveHTML method:

$htmlString = $dom->saveHTML($xpath_resultset->item(0));

这将为您提供该特定DOMNode及其所有子代的字符串表示形式.

This will give you a string representation of that particular DOMNode and all its children.
