Re: [xsl] Referencing unique values by their order number.

[Andreas Kemkes <a5sk4s@xxxxxxxxx>]

David:

Thank you.  Works like a charm.

I was trying to solve the problem
without keys first and then see if I can apply keys in case I need to speed it
up.

Part of the reason was that I had not used keys before, but the other
issue was a concern that I could not use keys in my context, which might have
been lost in the simplification of the example.

The real input example has
various sections of the original example - aside from being also more
convoluted in other aspects. All sections need to use their own unique value
set and reference it appropriately.  My concern was that the top-level (i.e.,
somewhat global) key feature wouldn't be appropriate.

Is there a way to do
the same without keys?

I will also study keys and the example expression a
bit more to understand how to make it work.

Thanks again,

Andreas
