Read ReadElementExtensions from RSS ATOM

I have the following code and I cannot deserialize a RSS ATOM feed to a class. The "team" node cannot be read and the rest of the properties don't seem to be getting filled. When I comment out the "team" node.

This is my code:

The URL of the RSS feed: http://www.volleybal.nl/application/handlers/export.php?format=rss&type=poule&standen=D3K&iRegionId=7000

    public static SyndicationFeed GetFeed(string feedUrl)
    {
        Uri serviceUri = new Uri(feedUrl);
        WebClient downloader = new WebClient();

        Stream responseStream = downloader.OpenRead(serviceUri);

        XmlReader responseReader = XmlReader.Create(responseStream);
        SyndicationFeed syndicationFeed = SyndicationFeed.Load(responseReader);
        return syndicationFeed;
    }

System.Collections.ObjectModel.Collection<Stand> oo = programFeed.ElementExtensions.ReadElementExtensions<Stand>("ranking", "http://www.nevobo.nl/competitie/");
