后台代码request.aspx代码如下：

{
Stream resStream = request.InputStream;

string st = str.ReadToEnd();
xmlDocument xmldoc = new xmlDocument();
xmldoc.loadxml(st);
System.Xml.XmlNodeList ndlist = xmldoc.GetElementsByName("site");
foreach (xmlNode xn in ndlist)

string ndvalue = xn.InnerText;
Response.Write("你选择的站点是："+ndvalue+"<br/>");
