The BBC provides a wide range of RSS news feed, e.g. UK Educational news
News Page
[edit | edit source]Reformat the RSS feed as 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>
Text-to-Speech
[edit | edit source]The Opera browser with Voice extension supports text-to-speech, allowing this news to be spoken. This uses the XML vocabularies VoiceXML and XML Events. [2019-01-26 : Sadly Opera no longer supports 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>
Note that the html namespace has been given a prefix, so that the default prefix can refer to the RSS feed.
Generic RSS reader
[edit | edit source]More generally, a reader which could voice any RSS feed would be a useful service.
