A (not so) simple python script to import Live Journal's XML export files to Day One for Mac.

lj-to-dayone

#!/usr/bin/python

# HOW TO USE THIS SCRIPT:
# 0. Install [Day One CLI](http://dayoneapp.com/tools/)
# 1. Get your XML files using [Live Journal's export form](http://www.livejournal.com/export.bml)
# 2. Run this script against every exported file (yes, you get tons of XML files — it's a good idea to automate this step). The shell command should look like this
#    `ls -1 *.xml | xargs -n1 lj-to-dayone -u username`
#    assuming you have all your XMLs in current directory and lj-to-dayone on your PATH (or in the same directory).
