分享怎样读程序中生成的XML代码？
objXML.load(strSourceFile)
如果不是要读本地的文件
而是读一段程序中生成的XML代码
要怎么写呢？

这个是我刚写完的无刷新的例子,应该很详细了:
userlist.asp代码:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>用户列表</title>
<script language="javascript">
function refresh()
{
//2秒自动刷新一次,2秒取得一次数据.
timer = window.setInterval("loadData()",2000);
}
</script>
<script language="javascript">
<!--
function loadData(sRoomName)
{
var xml = new ActiveXObject("Msxml2.XMLHTTP") || new XMLHttpRequest();
//var xml2=new ActiveXObject("Microsoft.XMLDOM");
xml.open( 'post', 'userlistserver.asp?roomname='+sRoomName, false );
xml.onreadystatechange = function()
{
if( xml.readyState == 4 )
{
if( xml.status == 200 )
oncomplete( xml );
}
}
xml.send(null);
}
function oncomplete( xml )
{
var xml = xml.responseXML; //接收server.asp输出的xml文档
var xmlDom=new ActiveXObject("Microsoft.XMLDOM");
xmlDom.async="false";
xmlDom.loadXML(xml.xml);
var root=xmlDom.selectNodes("//data/useritem"); //以useritem做为根结点
var str="";
for (var i=0;i<root.length;i++)
{
for (var j=0;j<root[i].childNodes.length;j++)
{
if (j==1)
str=str+"<img src="+root[i].childNodes[j].text+" width=20 height=18> ";
else
if ((j==1) || (j==2))
{
str=str+root[i].childNodes[j].text+" ";
}
}
str=str+"<br>";
}
userList.innerHTML=str;
-->
</script>
</head>
<body onload="javascript:loadData()">
<div id="userList"></div>
<input type=hidden id="roomname" value="<%=roomname%>" NAME="roomname">
</body>
</html>
server.asp代码:
