While browsing around remix.kwed.org for something nice to play while working today, I realized I was missing a scriptlet to make a play list of all mp3 files linked from any web page (and web plain web server directory listings in particular).
Enter the very convenient RFC 2397 data: URL protocol -- replacing that bit with a location='content-type,'+escape(page), and we're set. (The Mozilla data: testsuite is a handy resource to get a quick idea of what you can do with this toy and how, if you are new to the concept. It's still not widely supported in browsers, but good browsers do.)
Enjoy! - the Generate M3U playlist scriptlet, in its.
