之前解析都是XmlDocument.Load 而现在可以利用DynamicXml生成Dynamic对象实现强类型操作，很好用.

///

        ///         /// 
             public static DynamicXml ReturnDynamicXml(this string fileName) {            if (string.IsNullOrWhiteSpace(fileName))                return null;            try {                DynamicXml xmlObject = DynamicXml.Load(fileName);                Console.WriteLine(fileName + "-XML解析数据成功");                return xmlObject;            } catch {                Console.WriteLine(fileName + "-XML解析数据失败,任务中断");                return null;            }        }

public class DynamicXml : DynamicObject {        #region Fields        public XElement _root;        #endregion        #region .Ctor        private DynamicXml(XElement root) {            _root = root;        }        #endregion        #region Methods        ///

另外一是对HTML代码进行选择如下：

public class QueryHtmlNode    {        public void Go()        {            WebClient client = new WebClient();                       MemoryStream ms = new MemoryStream(client.DownloadData("http://www.44woool.com/"));            HtmlDocument doc = new HtmlDocument();            doc.Load(ms, Encoding.GetEncoding("gb2312"));            var trs = doc.DocumentNode.SelectNodes("//tr").Where(it => null != it.Attributes["bgColor"] && it.Attributes["bgColor"].Value.Equals("#FFFF99")).ToList();            foreach (var tr in trs)            {                Console.WriteLine(new string('#', 50));                #region --- 特定一些数据 ---                //if (null != tr.SelectSingleNode("td/font"))                //{                //    //时间                //    Console.WriteLine(tr.SelectSingleNode("td/font").InnerText);                //}                //if (null != tr.SelectSingleNode("td[2]/a[@href]"))                //{                //    //链接                //    Console.WriteLine(tr.SelectSingleNode("td[2]/a[@href]").Attributes["href"].Value);                //}                 #endregion                #region --- 所有 ---                //foreach (var td in tr.SelectNodes("td"))                //{                //    Console.WriteLine(td.InnerText);                //    foreach (var a in tr.SelectNodes("td/a[@href]"))                //    {                //        Console.WriteLine(a.InnerText + "---------" + a.Attributes["href"].Value);                //    }                //}                #endregion                #region --- 按列取数据 ---                var tds = tr.SelectNodes("td");                for (int i = 0; i < tds.Count; i++)                {                    switch (i)                    {                        case 0:                            Console.WriteLine("服务器名称:" + tds[i].InnerText);                            if (null != tds[i].SelectSingleNode("a[@href]"))                            {                                Console.WriteLine("URL:" + tds[i].SelectSingleNode("a[@href]").Attributes["href"].Value);                            }                            break;                        case 2:                            Console.WriteLine("开放时间:" + tds[i].InnerText);                            break;                        case 4:                            Console.WriteLine("版本介绍:" + tds[i].InnerText);                            break;                        case 5:                            Console.WriteLine("QQ:" + tds[i].InnerText);                            break;                        default:                            break;                    }                }                #endregion            }            Console.WriteLine(trs.Count());        }    }
