How can I view the raw XML of an RSS feed in Safari (or Reeder)?
Here’s a Safari extension to view the raw XML data: https://github.com/sergeche/xmlview#readme



There’s an online demo, too: http://media.chikuyonok.ru/xmlview/ This works in Firefox, Chrome, and Safari.

Edit: Sadly, this extension doesn’t work in Safari 5.1. There’s an issue for that here: https://github.com/sergeche/xmlview/issues/16



Alternatively, you could always open Terminal.app and just use curl to view the raw RSS/XML contents:

curl "http://example.org/some-feed.rss"
