I currently have a flat-file database I am trying to convert to WordPress, and want to import all my articles via RSS. I have tried to copy the WordPress XML format as much as possible, but have run into a wall. When importing from the XML file I created, WordPress only imports the last item. So, if I have four articles in the XML file, only the fourth is imported, even though all the articles are formatted the same.
I have tried to import XML files with different numbers of articles, and it always only imports the last item (no matter what that item is). I have also tried comparing my XML file with the one WordPress exports, but I can't find any difference.
My XML example file: http://www.undressmerobot.com/rss.xml
I am importing via Import > WordPress. I also tried Import > RSS, and that worked except that the categories didn't import. (Instead, a new blank category was created for every article imported. So, five articles imported, five new blank categories.)
