Well, you can create an EMF ResourceSet with the right BpmnFactory
loaded on it, and it will effectively take care of that.

This is EMF. You can read the model, and you can use a TreeIterator to
do some filtering and get the elements you are after.

EMF should help with most of what you try to achieve. You should load
the bpmn_diagram Resource, and it will load the semantic resource.
For the notation and appearances, you can modify the Nodes and the Edges
at will.
Thanks,

You should use the BPMN factory to read bpmn_diagram files I think.
