This is a WordPress eXtended RSS file generated by WordPress as an export of
|
|
your blog. It contains information about your blog's posts, comments, and
|
|
categories. You may use this file to transfer that content from one site to
|
|
another. This file is not intended to serve as a complete backup of your
|
|
blog.
|
|
|
|
To import this information into a WordPress blog follow these steps:
|
|
|
|
1. Log into that blog as an administrator.
|
|
2. Go to Manage > Import in the blog's admin.
|
|
3. Choose "WordPress" from the list of importers.
|
|
4. Upload this file using the form provided on that page.
|
|
5. You will first be asked to map the authors in this export file to users
|
|
on the blog. For each author, you may choose to map an existing user on
|
|
the blog or to create a new user.
|
|
6. WordPress will then import each of the posts, comments, and categories
|
|
contained in this file onto your blog.
