Also sounds fine to me. My solution definitely works, so the real
question is: what are the relative advantages/disadvantages between
these solutions? i.e. is it going to be relatively more efficient to
process in the second way versus the first, or do the XPath
expressions (which are effectively equivalent as far as I can tell)
get "mapped" to the same underlying implementation?
Modulo the efficiency issues (which I have no expertise on), the
relative advantages I can see are:
The advantage to Tony's way is that the element in question comes
first in the template, it says "give me all the corpauthor elements
with an ancestor of variablelist with the attribute set to so-and-so",
so it's more readable and self-documenting than my solution.
The advantage to my way is that it's a shorter XPath expression.
Thanks for the suggestion!
