利用Ajax傳遞Xml文檔

用戶端

<script language="javascript">

//產生XML檔案
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;
}

///向服務器發送XML文檔
function Send(Str,URL)
{
var Http = new ActiveXObject("Microsoft.XMLHTTP")
Http.open("POST",URL,false)
Http.send(Str)
return Http.responseText;
}

///獲得XML中指定的節的值
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>

伺服器端（test.cs）

System.IO.Stream stream = Request.InputStream
System.Xml.XmlDocument doc = new XmlDocument();
try
{
doc.Load(stream); //載入發送過來的Xml文檔
}
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);
}

//將doc處理後輸出以便返回到用戶端(此處省略)

response.write("")
