想說應該有這樣的東西,就找到「https://tools.ietf.org/html/new-rfcs.rss」這頁,本來以為直接就是 RSS feed 了 (因為網址),一打開來發現看起來像是個網頁,結果最上面這樣說明:
Don't panic. This web page is actually a data file that is meant to be read by RSS reader programs.
馬上打開來看 page source code,果然是 XSL!
<?xml-stylesheet title="CSS_formatting" type="text/css" href="css/rss.css"?> <?xml-stylesheet title="XSL_formatting" type="text/xml" href="rss2html.xsl"?>
好久沒看到這個了,大概是十年前想要做到資料與效果分離 (client-side rendering) 的方式...
