How do I display a DOMElement?

Question

I'm using readability's code to extract HTML from a web page. How do I display it on a page?

$content = grabArticle($webpage);
echo $content;

ERROR => Object of class DOMElement could not be converted to string...

Marc B's answer got me on the right track, but I had a similar need and this was the code I landed on:

$newdoc = new DOMDocument;
$node = $newdoc->importNode($node, true);
$newdoc->appendChild($node);
$html = $newdoc->saveHTML();
