$html = '';
foreach($parentElement->childNodes as $node) {
$html .= $dom->saveHTML($node);
}

This doesn't work if the childNodes have childNodes though – Ben G Aug 23 '11 at 05:34

@babonk That's not true. Look at the bottom of the CodePad. – alex Aug 23 '11 at 05:47

Weird, I got an error locally when I used it.. might be a version thing – Ben G Aug 23 '11 at 06:07

3@babonk `saveHTML()` with a node is only supported >= 5.3.6. You may need to use `saveXML()` if using a prior version. – alex Aug 23 '11 at 06:19

Inner HTML
Try approach suggested by @trincot:
$html = implode(array_map([$node->ownerDocument,"saveHTML"], iterator_to_array($node->childNodes)));
Outer HTML
Try:
$html = $node->ownerDocument->saveHTML($node);
or in PHP lower than 5.3.6:
$html = $node->ownerDocument->saveXML($node);
