Get inner HTML of parent element with php and xpath

问题

I'd like to get all of the content including tags of a parent element, let's say:

$imgs = $xpath->query('//img');
echo $imgs->item(0)->parentNode->innerHTML;

Of course, innerHTML attribute doesn't exist. The most similar attribute would be innerText that contains only text without tags. I really need the HTML. Is there a painless way to achieve this?

回答1:

You could use another XPath expression instead (of selecting the parent node and innerHTML), ./../node() which selects the parent element.

Using node() is important so you get both elements and text nodes.

If you know theres only one <img/> element, you can also use //*[img]/node().
