Question

I have the following code to parse an RSS feed:

$doc = new DOMDocument();                                                                                                                                                                                                                                                   
$doc->load('http://gdata.youtube.com/feeds/api/users/user/uploads?orderby=viewCount');
$arrFeeds = array();
foreach ($doc->getElementsByTagName('entry') as $node) {
  $itemRSS = array ( 
    'title' => $node->getElementsByTagName('title')->item(0)->nodeValue,
    'desc' => $node->getElementsByTagName('description')->item(0)->nodeValue,
    'link' => $node->getElementsByTagName('link')->item(0)->nodeValue,
    'date' => $node->getElementsByTagName('pubDate')->item(0)->nodeValue
  );
  array_push($arrFeeds, $itemRSS);
}

The feed is something like this:

<title type='text'>Handelswetenschappen</title>
<link rel='alternate' type='text/html' href='http://www.youtube.com/watch?v=eDiF7jVsoAQ&amp;feature=youtube_gdata'/>

With the code above, I am able to fetch the title and description.
What I need to know is how to get the link, so actually an attribute of the item ‘link’, the media:content url or the media:player url.

Answer 1

$link  = $element->getAttribute("href");

So I guess you’ll want something like this, modify the line where you’ve written:

'link' => $node->getElementsByTagName('link')->item(0)->nodeValue,

Change it to this:

'link' => $node->getElementsByTagName('link')->getAttribute('href'),
