2.將工程目錄下的WebForm1.ASPx中內容全部刪除，只留下頂部的一條語句：
<%@ Page language="c#" Codebehind="WebForm1.ASPx.cs" AutoEventWireup="false" Inherits="XMLTest.WebForm1" %>
3.修改WebForm1.ASPx.cs中內容，在Page_Load中加入:
XmlDocument doc=new XMLDocument();
String XMLfile=string.Empty;
xmlfile=Context.Request.PhysicalApplicationPath+(Request.QueryString["sel"].ToString()=="xml"?"\\hello.XML":"\\hello.xsl");
doc.Load(XMLfile);
Response.Write(doc.InnerXML);
4.在工程根目錄下新增test.htm,並設為工程首頁:
<Html>
<head>
<title></title>
</head>
<body>
<div id="resTree"></div>
<FONT face="宋體"></FONT><input type="button" value="執行" onclick="GetXML()"><BR>
<script language="JScript">
var srcTree,xsltTree,xt;
var http_request = false;
function GetXML()
{
srcTree = new ActiveXObject("MsXML2.FreeThreadedDOMDocument");
srcTree.async=false;
xsltTree= new ActiveXObject("MsXML2.FreeThreadedDOMDocument");
xsltTree.async = false;
xt=new ActiveXObject("MSXML2.XSLTemplate");
resTree.innerHtml="";
makeRequest("WebForm1.ASPx?sel=xml",GetXML_CB);
}
function makeRequest(url,callback) {
http_request = false;
if (window.XMLHttpRequest) { // Mozilla, Safari,...
http_request = new XMLHttpRequest();
if (http_request.overrideMimeType) {
http_request.overrideMimeType('text/XML');
}
} else if (window.ActiveXObject) { // IE
try {
http_request = new ActiveXObject("Msxml2.XMLHTTP");
} catch (e) {
try {
http_request = new ActiveXObject("Microsoft.XMLHTTP");
} catch (e) {}
}
}
if (!http_request) {
alert('Giving up :( Cannot create an XMLHTTP instance');
return false;
}
http_request.onreadystatechange = callback;
http_request.open('GET', url, true);
http_request.send(null);
}
function GetXML_CB() {
if (http_request.readyState == 4) {
if (http_request.status == 200) {
srcTree.loadXML(http_request.responseText);
makeRequest("WebForm1.ASPx?sel=xsl",GetXsl_CB);
} else {
alert('There was a problem with the request.');
}
}
}
function GetXsl_CB(){
if (http_request.readyState == 4) {
if (http_request.status == 200) {
xsltTree.loadXML(http_request.responseText);
xt.stylesheet=xsltTree;
var proc=xt.createProcessor();
proc.input=srcTree;
proc.transform();
resTree.innerHtml=proc.output;
} else {
alert('There was a problem with the request.');
}
}
}
function makeRequest(url,callback) {
http_request = false;
if (window.XMLHttpRequest) { // Mozilla, Safari,...
http_request = new XMLHttpRequest();
if (http_request.overrideMimeType) {
http_request.overrideMimeType('text/XML');
}
} else if (window.ActiveXObject) { // IE
try {
http_request = new ActiveXObject("Msxml2.XMLHTTP");
} catch (e) {
try {
http_request = new ActiveXObject("Microsoft.XMLHTTP");
} catch (e) {}
}
}
if (!http_request) {
alert('Giving up :( Cannot create an XMLHTTP instance');
return false;
}
http_request.onreadystatechange = callback;
http_request.open('GET', url, true);
http_request.send(null);
}
</script>
</body>
</Html>
5.運行工程，看看效果吧!

xml文檔只有純粹的數據，如果需要顯示到html頁面中的話，一般需要使用定制的xsl文檔來解析，或者手工通過JS來讀取XML中的值顯示到Html中的dom樹中，當使用xsl文檔來解析時，相應的xml文檔中必須指定對應的xsl文檔才能正常顯示，但當有些程序動態輸出xml文檔時，並沒有指定相應的xsl文檔，這時就必須通過其它途徑來加載相應的xsl文檔來解析，當然，在服務器端輸出xml文檔時，通過一些xml api也可以實現，我這兒描述的是通過JS來實現的一種方式。用這種方式的話，就拋開了服務器平台的限制，服務器端只需要輸出相應的XML文檔(.Net/J2EE都可以)，並且將對應的xsl文檔輸出給客戶端（可以輸出流或直接在客戶端加載xsl文檔)。
這裡有幾個需要注意的地方，我們一般是使用Msxml2.Document組件來加載xml文檔的，但當動態使用xsl解析xml文檔時，必須使用Msxml2.FreeThreadedDOMDocument這種自由線程的組件，同時使用MSXML2.XSLTemplate模板組件來加載xml,xsl數據，通過MSXML2.XSLTemplate的transform方法，就可以動態的用xsl來解析xml數據了,另外，IE5開始，系統默認的xml組件是msxml2，如果需要使用更新的msxml組件需要安裝更新的msxml組件包，並指定新的名稱，例如Msxml2.FreeThreadedDOMDocument.4.0，現在最新的msXML組件是6.0beta，可在M$網站下載。
