How to get html code of DOMElement node?

Question

I have this html code:

<html>
    <head>
    ...
    </head>
<body>
    <div>
    <div class="foo" data-type="bar">
        SOMECONTENTWITHMORETAGS
    </div>
    </div>
</body>

I already can get the "foo" element (but only its content) with this function:

private function get_html_from_node($node){
  $html = '';
  $children = $node->childNodes;

  foreach ($children as $child) {
    $tmp_doc = new DOMDocument();
    $tmp_doc->appendChild($tmp_doc->importNode($child,true));
    $html .= $tmp_doc->saveHTML();
  } 
  return $html;
}

But I'd like to return all html tags (including its attributes) of DOMElement. How I can do that?

If you are trying to get `html_from_node` `class="foo"` you are doing it not correct. There is much easy and short way of doing this. — s.webbandit, Oct 16 '12 at 07:47

Note: This is not duplicate, as it's asking to return html of DOMElement, not DOMDocument as in other question, and these questions have already different answers. — kenorb, Feb 21 '15 at 14:55

Use the optional argument to DOMDocument::saveHTML: this says "output this element only".

return $node->ownerDocument->saveHTML($node);

Note that the argument is only available from PHP 5.3.6. Before that, you need to use DOMDocument::saveXML instead. The results may be slightly different. Also, if you already have a reference to the document, you can just do this:

$doc->saveHTML($node);

This is actually what I need but it's for an WordPress plugin which should work with version 3.4 and this versions requires php 5.2.4. – Xaver Oct 16 '12 at 07:57
@revaxarts Then use `saveXML`. The output will be little different... – lonesomeday Oct 16 '12 at 08:01
u point me to a full example? I don't have a reference of the document in the function only the node and `DOMDocument::saveXML($node)` is not working same as `$node->saveXML($node)` – Xaver Oct 16 '12 at 08:08

@revaxarts The code you'll need is `$node->ownerDocument->saveXML($node)`. – lonesomeday Oct 16 '12 at 08:09
ok, great thanks! Is there a documentation what is different to `saveHTML` and which php version is required? – Xaver Oct 16 '12 at 08:11
@revaxarts See the two PHP manual pages linked in my answer. – lonesomeday Oct 16 '12 at 08:13

I can't post full code as an answer, but this answer is incorrect. Here's the working code: https://gist.github.com/komlenic/1374083 – c00000fd May 31 '20 at 01:56
This answer is incorrect @c00000fd You are a life saver ... your link saved my life. – Clain Dsilva Aug 21 '20 at 15:23
That code surely does something entirely different, @ClainDsilva. – lonesomeday Aug 21 '20 at 15:58
