Track a Null COMP

Hello,

I have a Null COMP that is following the position of a path.
I’d like to know the exact position of the Null.
I’ve tried to reference a SOP using localTransform, but it doesn’t get all the frames.
If I right click on the Null, I can see that has a couple of parameters that are showing exact position : Local Origin and World Origin.
How can I access to them?

Thanks

Object CHOP?

Thanks, sir
