If I understand you right, then you mean by preceding also the
ancestors and by following also the descendants.

Do
   (preceding::tab | ancestor::tab)[@id][last()]/@id
and
   (following::tab | descendant::tab)[@id][1]/@id
fulfill your requirements?

Did you manage to find the deepest tab[@state='on']?

Cheers,
Oliver
