RSS-feed shows no posts

Ok, I found it is probably because links to the post contains the &-sign which XML doesn’t like. How do I replace the sign with the XML-friendly & in the feed?

I somewhat fixed. fimp.dk is a metablog and it was one incoming blog that was making the trouble. So I ran that particular blogs feed through Yahoo Pipes before putting it into mine.

Actually, I oversaw something and the Yahoo Pipes workaround didn’t work. I thought it was “cleansing” the feed for errors but it didn’t. So if anyone knows how to replace & with & in the feed it would be great if you could share it.
