What I was doing was refactoring some RSS code that didn't have enough 
tests, so I wanted to compare pretty much every element of the 
resulting RSS. I ended up just eyeballing it in an aggregator, which 
seems to have worked out okay but still wasn't ideal.

I'd want a pretty granular comparison, and at the API level would be 
ideal. I don't mind having to do a little work to format the changes 
into readable output. Also, maybe having API-level information would 
make it easier for me to filter out certain differences.
