I have changed the script to run on the command-line and removed the graphical interface. Also note the added shebang #!/usr/bin/env python3

Thanks for this.
I have updated it to work with Python3 here - https://github.com/josylad/WordPress-XML-Splitter

My version must be python3-only since they changed print "x" to print("x") there.

it theres way to split based on an criteria

for exmaple split only nodes based on an critereia of filter
