Import posts, comments, users, and categories from a BlogML file.
Based on BlogML importer written by Aaron Lerch (
http://www.aaronlerch.com/) and modified to work with Wordpress 3.0.
Note: Plugin may not import categories or tags properly into WordPress. For instance,
during my install there were no tags installed, and the categories were defined as GUIDs.
A simple rename and retag fixed this issue.
