Ajax Server：

XmlDocument xmldoc = new XmlDocument(); 
xmldoc.Load(Request.InputStream);//接收到客戶端傳來(lái)的xml 
XmlNode rootnode = xmldoc.DocumentElement; 
XmlNode pwd = rootnode.SelectSingleNode("pwd"); 
pwd.InnerText = "changed";//服務(wù)器端改變xml文檔內(nèi)容 

Response.Write(xmldoc.InnerXml);//返回修改后的Xml文檔 
Response.End(); 
}
