There are mainly two ways (both should work from CLI in batch mode).

One way is to write an exporter. This does not get the internal objects 
but drawing commands. For a converter it is useful only if you want to 
extract graphical information.

The other way is writing a script that creates an action. The action then 
does a search on the design objects and query the objects one by one from 
the search list.

I am not sure I have full support for all kind of objects yet, but I am 
sure I can fix bugs or add features in short turnaround times. If you are 
still in Hungary, we can even meet and arrange an intensive coding 
session.

The tutorial is the rosetta subproject that offers a few scripts at 
different difficulty levels to demonstrate and explain how to do things. I 
believe the most relevant example for you is 
http://repo.hu/projects/pcb-rnd/gpmi/rosetta/30_move/index.html

There is also a scripting doc at 
http://repo.hu/projects/pcb-rnd/gpmi/index.html

I can provide support with the installation in private, if required.
