</xsl:template>
What this does:
* Collapse the templates together for all p elements inside note,
rather than splitting a template out for the first p. This is
clearer, allows better code reuse, and is more robust.
I agree (about the robustness), and it works perfectly.
Interestingly, it's also an exception to the general principle that
more templates are usually better. In this case, I think that's a
consequence of how the rules limit what expressions can be used as
match patterns (so, for example, the pattern "note/descendant::p[1]"
is illegal), plus the fact that in this case the special treatment
isn't exclusive of the general treatment (both sorts of p become
p[@class='note_p']).
As an aside -- this code assumes that you'll never have notes nested
inside your notes. If you do, amend the test to look at
ancestor::note[1]/descendant::p[1] (and maybe watch out for more edge cases).
Cheers,
Wendell
