Thank you for the reply!
I really hated bumping so much, and I hate it when others do, but I made my first post five days ago, and this is the first response. If I hadn't bumped, it would have been on the 10th page by now, and lost forever. I've tried to be constructive with my bumps, but I apologise for doing it as much as I did.
My old blogger page generated an atom feed. I've managed to figure out the problem with importing the old blogger entries, so that won't be a problem now, fortunately.
The blog, since I moved it to wordpress, was an RSS feed. I retrieved the backup of the feed archive by exporting them from Google Reader. I don't know if this is in atom format or rss. I did one export which only retrieved the rss archive from reader, after I'd stopped using atom. Could that still be a problem?
Here's the first bit of one of the xml files I'm trying to import:
<feed xmlns:gr="http://www.google.com/schemas/reader/atom/" xmlns:media="http://search.yahoo.com/mrss/" xmlns="http://www.w3.org/2005/Atom"><!--

I note that both "atom" and "mrss" are mentioned in the header. Is this a problem? If so, does anyone know how to choose the format that Google Reader can export to? This is the method I usedto get the feed history: http://googlesystem.blogspot.com/2007/06/reconstruct-feeds-history-using-google.html
Thank again so much for your reply. With a little direction I'm sure I can figure this out.
