This is how you list the latest number (whatever you want the number to be - i.e. 5, 7, 10 etc) posts from the blog you are viewing it for.
http://blogname.blogspot.com/search?max-results=N
Instead of N, type in the number of posts.
If the blog has less than 1000 posts, you can view/save your search page by typing the following:
http://blogname.blogspot.com/search?max-results=1000
This is how you get all the posts in an XML feed. This is a good format if you intend to import it in a database. Type:
http://blogname.blogspot.com/feeds/posts/default?max-results=1000
