foreach (XmlNode itemnode in node.ChildNodes)
            {
                string title = "";
                string url = "";
                Article art = null;
                    foreach (XmlNode tempnode in itemnode.ChildNodes)
                    {              
                          title = tempnode.Attributes[0].Value.ToStrin();                  
                          url = tempnode.Attributes[1].Value.ToString();                 
                    }
                    art = new Article(title, url);
                    rssfeed.Articles.Add(title, art);           
             }

请大家帮我看下这几行代码，我的目的是把内循环中title和url得到的值每次保存进下面的rssfeed.Articles.Add（）中，可是当循环到第二遍时，就是不跳进外循环的方法中去，不知是什么原因？请各路大侠指教？

非常感谢了
