BBC 提供了各种 RSS 新闻源，例如 英国教育新闻
将 RSS 提要重新格式化为 HTML
declare option exist:serialize "method=xhtml media-type=text/html";
let $news := doc("http://newsrss.bbc.co.uk/rss/newsonline_uk_edition/education/rss.xml")
let $dateTime := $news/rss/channel/lastBuildDate
return
<html>
<body>
<h2>Education news from the BBC at {string($dateTime)}</h2>
{ for $newsItem in $news/rss/channel/item[position() < 10]
return
<div>
<h4>{string($newsItem/title)}</h4>
<p>{string($newsItem/title/description)} <a href="{$newsItem/link}">more..</a></p>
</div>
}
</body>
</html>
带语音扩展的 Opera 浏览器支持文字转语音，允许将此新闻朗读出来。 这使用 XML 词汇 VoiceXML 和 XML 事件。 [2019-01-26 : 遗憾的是，Opera 不再支持 VoiceXML]
declare option exist:serialize "method=xhtml media-type=application/xv+xml";
let $news := doc("http://newsrss.bbc.co.uk/rss/newsonline_uk_edition/education/rss.xml")
let $dateTime := $news/rss/channel/lastBuildDate
let $newsItems := $news/rss/channel/item[position() < 10]
return
<h:html xmlns:h="http://www.w3.org/1999/xhtml"
xmlns:vxml="http://www.w3.org/2001/vxml"
xmlns:ev="http://www.w3.org/2001/xml-events"
>
<h:head>
<h:title>BBC Education news</h:title>
<vxml:form id="news">
<vxml:block>
{for $newsItem in $newsItems
return string($newsItem/description)
}
</vxml:block>
</vxml:form>
</h:head>
<h:body>
<h:h1>BBC Education news at {string($dateTime)}</h:h1>
<h:p>
<h:a ev:event="click" ev:handler="#news" >
<h:img src="http://www.naturalreaders.com/images/laba.gif"/>
</h:a>
(Requires the Opera Browser with Voice extension)
</h:p>
{ for $newsItem in $newsItems
return
<h:div>
<h:h4>{string($newsItem/title)}</h:h4>
<h:p>{string($newsItem/description)} <h:a href="{$newsItem/link}">more..</h:a></h:p>
</h:div>
}
</h:body>
</h:html>
请注意，html 命名空间已指定前缀，以便默认前缀可以引用 RSS 提要。
更一般地说，可以朗读任何 RSS 提要的阅读器将是一项有用的服务。
