java xsl解析xml,调用xsl来解析xml文档(js异步)

1.新建一个vs2003的web工程,取名为XMLTest

2.将工程目录下的WebForm1.aspx中内容全部删除，只留下顶部的一条语句：

3.修改WebForm1.aspx.cs中内容，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.在工程根目录下新增test.htm,并设为工程首页:

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);

}
