LINQ to XML 简单的小例子

 XDocument xml = XDocument.Load("http://rss.sina.com.cn/news/marquee/ddt.xml");
        var news = from x in xml.Descendants("item")
                   select new
                   {
                       name = x.Element("title").ToString(),
                       url = x.Element("link").ToString()

                   };
        foreach (var e in news)
        {
            lbl001.Text += e.name + " - " + e.url + "<br/>";
        }
