Iterating hierarchy for selection's top node

I have a few custom operator types, something like this
/obj/<custom_group>/<custom_ref>/<custom_ref>/<custom_geo>

Suppose I select custom_geo and I wanted to get to get its root node, /obj/<custom_group>/<custom_ref>, I had wanted to create a function that iterates.. If it is <custom_ref>, use .parent() and check again until if <custom_group> is 'hit', get the last <custom_ref> that was iterated?

The level of hierarchy can be different, the above is a simple example. Any ideas?
