Anyway, I wanted to export it all. It's all text, no images.
Blogger export does a rather heavy atom / xml document, which to be honest isn't really usable. I thought about hacking up / reusing some java sax/dom nonsense, but i'm too lazy and it's too late.
One suggestion which like (and which works well enough) is:
- view all the posts on one page,
e.g. goto http://yourblog.blogspot.com/search?max-results=100 (as appropriate)
- use the browser's 'save as' function, I chose "text"
- edit the file...
