sorry for the late reply.  I suspect that by now you might have come up
with a solution yourself, so I'll keep my answer brief for now:

I think you need to return a set of nodes, whereas you have a set of
strings, and a string as such isn't a node.

If the above is too obscure, please let me know, and I'll elaborate! :-)
