Is there another way except ->ownerDocument->saveXML() to get node html with tags

Question

As we know, to get node html with its inner tags we have to use

$node->ownerDocument->saveXML($node);

instead of

$node->nodeValue;

because the last method strips all the inner tags

But what if I get a node like

$dom->getElementsByTagName('tr')[2]->getElementsByTagName('td')[5]

How can I get its html with its inner tags without writing lines like

$dom->getElementsByTagName('tr')[2]->getElementsByTagName('td')[5]->ownerDocument->saveXML($dom->getElementsByTagName('tr')[2]->getElementsByTagName('td')[5])

Is there another shorter way?

Answer 1

You didn't well understand what DOMNode::ownerDocument is. This property returns nothing more than the DOMDocument instance to which the DOMNode instance belongs ( $dom in your code).

So you can replace your long line with:

$cell = $dom->getElementsByTagName('tr')[2]->getElementsByTagName('td')[5];
echo $dom->saveXML($cell);

Note that you can also shorten your code using DOMXPath.

$xp = new DOMXPath($dom);
echo $dom->saveXML($xp->query('//tr[3]/td[6]')->item(0));
