<script type="text/javascript">

var request;

var Ready_State_Loading = 1;

var Ready_State_Loaded = 2;

var Ready_State_Interactive = 3;

var Ready_State_Over = 4;

	function SendRequest(){

		request = InitXMLHttpRequest();

		if(request){

			request.onreadystatechange = OnReadyState;

			request.open("GET","data.xml",true);

			request.setRequestHeader("Content-type","text/xml");

	}

	function InitXMLHttpRequest(){

			var xRequst = null;

			if(window.XMLHttpRequest){

				return new XMLHttpRequest();

			else{

				return new ActiveXObject("Microsoft.XMLHTTP");

			}

	}

	

	function OnReadyState(){

		var oDiv = document.getElementById("myDiv");

		var ready = request.readyState;

		var date = null;

		var message =oDiv.innerHTML;

		if(ready == Ready_State_Over){

			message += request.requestText;

		}

		oDiv.innerHTML = message;

	}

	

	window.onload = function(){

		SendRequest();	

	}

</script>

</head>



<body>

<div id="myDiv">

</div>

</body>

</html>

其中data.xml文件里的内容为

<table>

	<tr>

		<td>

		test

		</td>

	</tr>

</table>

结果运行时获取不到XML的内容，为什么？？？
