read attribute using XDocument and LINQ

I'm trying to parse a rss feed. I can get the elements out, but whatever i try, i cant get the attributes!

This is how the rss feed (xml) looks like:

<?xml version="1.0" encoding="UTF-8" ?>
<rss version="2.0">
  <channel>
    <title>nu.nl - Algemeen</title>
    <copyright>Copyright (c) 2010, nu.nl</copyright>

                <enclosure url="http://media.nu.nl/m/m1cz4nqakofe_t.jpg" type="image/jpeg" />      </item>

The attribute i'm trying to get is the 'enclosure url'.

This is my try:

private IEnumerable<Channel> getChannelQuery(XDocument xdoc)
    {

        return from channels in xdoc.Descendants("channel")
        开发者_开发知识库    select new Channel
            {
                Title = channels.Element("title") != null ? channels.Element("title").Value : "",
                Link = channels.Element("link") != null ? channels.Element("link").Value : "",
                Description = channels.Element("description") != null ? channels.Element("description").Value : "",
                //PubDate = channels.Element("pubDate") != null ? channels.Element("pubDate").Value : "",
                //Enclosure = channels.Element("enclosure ") != null ? channels.Element("enclosure").Value : "",
                Items = from items in channels.Descendants("item")
                    select new Item
                    {
                        Title = items.Element("title") != null ? items.Element("title").Value : "",
                        Link = items.Element("link") != null ? items.Element("link").Value : "",
                        Description = items.Element("description") != null ? items.Element("description").Value : "",
                        Guid = (items.Element("guid") != null ? items.Element("guid").Value : ""),
                        PubDate = (items.Element("pubDate") != null ? items.Element("pubDate").Value : ""),
                        Enclosure = (items.Attribute("url") != null ? items.Attribute("url").Value : "")
                    }
            };
    }

What am I doing wrong here?

Isn't it

Enclosure = (items.Element("enclosure").Attribute("url") != null ? items.Element("enclosure").Attribute("url").Value : "")

?
