How to get full HTML from DOMXPath::query() method?
提问by Milo? ?akonovi?
I have document from which I want to extract specific div with it's untouched content. I do:
我有一个文档，我想从中提取特定 div 的未修改内容。我愿意：
$dom = new DOMDocument();
$dom->loadHTML($string);//that's HTML of my document, string
and xpath query:
和 xpath 查询：
$xpath = new DOMXPath($dom);
$xpath_resultset = $xpath->query("//div[@class='text']");
/*I'm after div class="text"*/
now I do item(0)method on what I get with $xpath_resultset
现在我做item(0)我得到的方法$xpath_resultset
$my_content = $xpath_resultset->item(0);
what I get is object (not string) $my_content which I can echo or settype() to string, but as result I get is with fully stripped markup?
我得到的是对象（不是字符串）$my_content，我可以将其回显或 settype() 到字符串，但结果我得到的是完全剥离的标记？

Just pass the node to the DOMDocument::saveHTMLmethod:
只需将节点传递给DOMDocument::saveHTML方法：
$htmlString = $dom->saveHTML($xpath_resultset->item(0));
This will give you a string representation of that particular DOMNode and all its children.
这将为您提供该特定 DOMNode 及其所有子节点的字符串表示。
