How do I diff an RSS feed against last time it was run?

1

I have a feed - for example

2011 Patents of ultraviolet screens

If I run this next week, I would like to see if there had been an update since last time I looked - are there any feed readers that does this?

Pretty much all feed readers do this, I'd recommend Google Reader. If you were looking for a way of automating the process (like if you want a shell script to check every week), please clarify and I'll try to provide an example.

Yes please. You actually beat me to it. I used Firefox and it did not show any diff or "read" like Google reader does now I have tried it. – mplungjan – 2011-05-09T11:58:32.717

Firefox also has some extensions could give you the features you want. – user – 2011-05-10T04:25:04.223
