[bioontology-support] is-a transitive closure (path to root)

I would like to obtain the is-a transitive closure generated by the annotator as described here:

To get that, I am trying to get the path to the root for a concept (in an ontology), using the the is_a relations.

I found this:

But I do not know exactly how to extract & parse the path (list of nodes) from the XML returned.


This should get the path from concept ID 33934002 to root, in SNOMED.

Can you help?

Thank you,
Adrian Bivol.
