核心提示:客户端<script language="javascript">//生成xml文件 function GetAllFormData() { var strXML = "<Client>\r\n<FormData>\r\n"; strX

客户端

<script language="javascript">

//生成xml文件
function GetAllFormData()
{
   var strXML = "<Client>\r\n<FormData>\r\n";
   strXML += "<UserName>bccu</UserName>"
   strXML += "<Age>25</Age>";
   strXML += "</FormData>\r\n</Client>"
   return strXML;
}
 
///向服務器发送XML文档
function Send(Str,URL) 
{
   var Http = new ActiveXObject("Microsoft.xmlhttp")
   Http.open("POST",URL,false)
   Http.send(Str)
   return Http.responseText;
}
 
///获得XML中指定的节的值
function GetXMLNodeValue(strXML,nodeName)
{
   var Dom = new ActiveXObject("Microsoft.XMLDOM")
   Dom.async=false 
   Dom.loadXML(strXML)
   if(Dom.parseError.errorCode != 0) 
   {
     delete(Dom)
     return(false)
   }
   else
   {
     var node = Dom.documentElement.selectSingleNode("//"+nodeName);
     if(node)
       nodeValue = node.text;
     delete(Dom)
     return(nodeValue);
   }
}

 function Test()
 {
   var tmp    = Send(GetAllFormData(),"./test.aspx");
   var name    = GetXMLNodeValue(tmp,"UserName");
   var passWord  = GetXMLNodeValue(tmp,"Age");
 }
</script>


服务器端(test.cs)

System.IO.Stream stream = Request.InputStream
System.Xml.XmlDocument doc = new XmlDocument();
try
{
  doc.Load(stream); //加载发送过来的Xml文档
}
catch
{
  byte[] buffer = new byte[stream.Length];
  stream.Read(buffer,0,buffer.Length);
  string strXML = System.Text.UnicodeEncoding.Default.GetString(buffer,0,buffer.Length);
  doc.LoadXml(strXML);
}

//将doc处理后输出以便返回到客户端(此处省略)

response.write("")
