Transport Wordpress Export XML File to MODX Revolution
This is a standalone tutorial package, NOT an Extra you install via the Manager.
Just Download the zip, add it to your root MODX install, run it and then delete it.
Possible error points
- the script assumes no database table prefix names. It's looking for
modx_site_content
etc. - if the database is not utf8 there may be encoding issues
