That didn't help matters then...

Not really.  The longer it takes someone to decipher your requirements
from wordy descriptions and unhelpful examples the more likely it is you
won't get a response (which is unusual here).

Maybe try again but this time only put values in the example result that
can be obtained from the example documents... (and remove all
elements/atts from the example docs that aren't relevant to problem).
