Answer 1

using System.Linq;
using System.Xml.Linq;            XDocument doc = XDocument.Load("c:\\1.txt");
            var nodes = doc.Descendants("order");
            foreach (var item in nodes)
            {
                var vs = item.Descendants("step");
                foreach (var v in vs)
                {
                    MessageBox.Show(item.Element("mailNo").Value + ":" + 
                        v.Element("acceptTime").Value + " " +
                        v.Element("re").Value );
                }
            }

Answer 2

 XDocument doc = XDocument.Load("c:\\1.txt");我把xml值赋给了string xml
 XDocument doc = XDocument.Load(xml);
这样不可以啊。

Answer 3

XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(@"c:\test.xml");
XmlNodeList orderList = xmlDoc.SelectNodes(@"//orders/order");
foreach (XmlNode order in orderList)
{
Response.Write("mailNo:" + order["mailNo"].InnerXml + " ");
foreach (XmlNode step in order.SelectNodes(@"steps/step"))
Response.Write(step["acceptTime"].InnerXml + " " + step["re"].InnerXml + "<br/>");
Response.Write("<br/>");
}
