本文提供了一段完整的 JavaScript 代码，演示如何在网页中通过 ActiveXObject 或 DOM 接口加载并解析 RSS 数据源。代码展示了如何获取频道标题及文章列表，并将标题与链接动态渲染到页面容器中，适用于旧版 Internet Explorer 或支持标准 DOM 的浏览器环境。
具体实现代码如下所示：
HTML 页面结构与容器<html>
<head>
<title>javascript读取RSS数据</title>
<META content="text/html; charset=utf-8" http-equiv=Content-Type />
</head>
<body leftmargin="0" topmargin="0">
<font><h3 align="center">javascript读取RSS数据</h3></font>
<br>
<table width="90%" align="center" border="0" cellpadding=0 cellspacing=0>
<tr>
<td bgcolor=White><b>新闻中心</b><font size="-1">(摘自新浪网)</font><hr></td>
</tr>
<tr>
<td bgcolor=White>
<div id="container" >News Loading...</div>
</td>
</tr>
</table>
