Hi,

Given XSLT 2.0, you can select two elements $a and $b, and then the number
of elements between these two is
count($b/preceding-sibling::*) - count($b/preceding-sibling::*) - 1
This is probably more efficient than
count(*[. >> $a and $b >> .])
but you can use that if it's more convenient.
This answers the question as posed.
A better solution, however, might be available if you specified your
count differently.
For example, you might be better off asking "how do I count notes
elements that do not have book or author element ancestors", or "how
do I count notes elements that are directly inside books, but not
deeper". (From your problem statement it's impossible to know whether
one of these might not be the case.)
Cheers,
Wendell
