RE: XQuery question

I'm not completely sure I understand what you need, but here's a query on
your data that might give you some ideas:

distinct-values(tokenize(string-join(//link/@targets[. |= $id], ' '),
'\s+'))

This will give you a list of (distinct) letters that you can iterate over.
(If you'd rather have it as a single string, in the format of the targets
attribute, just string-join it again.)  Note that I have no idea whether
this is in fact faster than your current approach -- I suspect it does
much the same thing under the covers.
