Scripting/Parsing Apple Motion 5 .motn files

I'm new to animating and I've started using Apple Motion 5

http://www.apple.com/au/final-cut-pro/motion/

The interface can be a bit annoying by not letting me do things in bulk or automate things. Since it saves files in a nice xml format I've been kinda hacking it to do things I like.

e.g setting Fixed Resolution off for hundreds of assets wasn't possible in the app without doing each one manually so I wrote a short script to find and replace this line in the file setting value to 0

<parameter name="Fixed Resolution" id="113" flags="8606711808" default="1" value="0"/>

Are there any python libraries that parse/script .motn files? (other than generic xml parsers)

Try Awesome Python at https://github.com/vinta/awesome-python

Maybe you'll find there what you're looking for.

But if you really want to use cool app try The Foundry Nuke or Blackmagic Fusion instead of Apple Motion or Adobe After Effects. Nuke and Fusion are node-based flexible and powerful compositing applications that support python scripting and programming. There are non-commercial free versions:

Hope this helps.
