The Feed Sanitizer takes any news feed and turns it into straight, normalized RSS 2.0 / ATOM 1.0. This comes in handy if you are confronting with tangled or messed or knocked up feeds that are barely well-formed and want to parse these with a not-so-solid piece of software. The Feed Sanitizer scrubs off the dirt and returns germ-free feeds.
I was having a lot of trouble with my Drupal feed aggregator rejecting my blog's feed. I ran it through this sanitiser and it seems to be working trouble free now. Just use the sanitised link this page provides, as your new feed URL.
Heiko Behrens built The Feed Sanitizer with Python and djangoappengine using several open-source libraries such as feedparser by Mark Pilgrimand SyntaxHighlighter by Alex Gorbatchev. RSS and ATOM icons were provided by courtesy of feedicons.com and blogage.de. The Feed Sanitizer is open source with its source code on Github.
