php - How to return outer html of DOMDocument?

Question

I'm trying to replace video links inside a string - here's my code:

$doc = new DOMDocument();
$doc->loadHTML($content);
foreach ($doc->getElementsByTagName("a") as $link) 
{
    $url = $link->getAttribute("href");
    if(strpos($url, ".flv"))
    {
        echo $link->outerHTML();
    }
}

Unfortunately, outerHTML doesn't work when I'm trying to get the html code for the full hyperlink like <a href='http://www.myurl.com/video.flv'></a>

Any ideas how to achieve this?

As of PHP 5.3.6 you can pass a node to saveHtml, e.g.

$domDocument->saveHtml($nodeToGetTheOuterHtmlFrom);

Previous versions of PHP did not implement that possibility. You'd have to use saveXml(), but that would create XML compliant markup. In the case of an <a> element, that shouldn't be an issue though.
