First off, you should be using getElementsByTagNameNS since you are
working with a namespaced document. I am assuming its a Yahoo Media RSS
feed, so you would get the elements via:
$r = $doc->getElementsByTagNameNS("http://search.yahoo.com/mrss/",
"content");

Then to output the url attribute value:

foreach ($r AS $elem) {
    echo $elem->getAttribute("url") . "\n";
}

Hi. Our site http://rssphp.blogspot.net is working on providing possible solutions to the problem with different parsing methods in PHP. It's worth to have a look at the options.

$node = $r->item($i);
if ($node->hasAttribute('url') {

That should give you an array called $url of all the url attributes in
the nodes.

$url[] = $node->>getAttribute('url');
should be
$url[] = $node->getAttribute('url');

and don't forget to validate it before spitting it back out on a page
somewhere ...
