It's frustrating when a site doesn't advertise it's feed. Yes, you can look at the page source but you shouldn't have to. So, I made a little tool to find the available feeds given a url.
Here's how it works:
- load the page source and get all 'link' tags
- check each link to see it has the 'rel' attribute that contains 'alternate'
- if so, check for 'title' and 'href'
- test if the href value is a valid RSS or Atom feed using the same feed library as /reader
- if so, display the title and href value as a form
I've built this into the feed admin for /reader so that I can enter a page url, be presented with the available feeds, and subscribe with a single click.
Love it!
