This is a stupid Greasemonkey script which looks at a BBC podcast listings page and generates an OPML file. It’s a 20 minute hack and so is hard-coded for the Radio 4 podcasts – another five minutes should fix this. For the time being, try it out here.
I wanted to be able to import the file into my N95 so that I could browse them and import the ones I wanted. It seems to have done the job.
