In short:

* its possible save even into ONE self-recursive table
* may be it is more effective use 2 or few tables for different XML objects.

Btw, another way do queries on recursive structures which was invented not
so far, is XPATH. Another dream to be implemented in Valentina also.

Let me know if above 2 ways need more details from me.

If you plan use only LOCAL db engine, you can do this task of searches the
most effective with API methods of Valentina and Sets.

Write simple enough recursive method which go down and down and on each
level you keep own Vset of found records.
