利用Ajax传递Xml文档

客户端
<script language="JavaScript">
//生成XML文件
function GetAllFormData()
{
    var strXML = "<Client>rn<FormData>rn";
    strXML += "<UserName>bccu</UserName>"
    strXML += "<Age>25</Age>";
    strXML += "</FormData>rn</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("")
