利用Ajax传递Xml文档

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("")
