Hi Thomas,
sorry, I dont want to bother you. But in fact that is not what I'm
looking for. Maybe its my fault that I mixed a - as I thougt - related
problem in my second mail.
What I try to do is reduce redundancy. I cannot see where my
explanations differ. In fact, I started with something like your
example. But from a redundancy point of view
thats a mess so I tried to improve it. I came to something like
\startxmlsetups xml:chapter
\startchapter[
title={\xmlatt{#1}{title}},
number=\xmldoifelse{#1}{./attribute('num')}{yes}{no},
ownnumber=\xmldoifelse{#1}{./attribute('num')}{\xmlatt{#1}{num}}{}
]
\xmlflush{#1}
\stopchapter
\stopxmlsetups
which works fine and at least in my eyes has a clearer structure, but
still some redundancy. Now is the point where I think the
misunderstandings started, because now I tried two different approaches to
decrease redundancy: First step i tried to simplyfy *this* setup and
came to something like
\startxmlsetups xml:chapter
\startchapter[
title={\xmlatt{#1}{title}},
\xmldoifelse{#1}{./attribute('num')}{ownnumber=\xmlatt{#1}{num}}{number=no},
]
\xmlflush{#1}
\stopchapter
\stopxmlsetups
which would nicely eliminate every redundance but doesn't work and
complains about the mystery "missing or ungrouped '='"
The other attempt was - though i have not only to deal with chapters but
up to about 15 hierarchies, all structured in a similar way,
so I tried to delegate the processing like
\startxmlsetups xml:fillTitleAtts
title={\xmlatt{#1}{title}},
number=\xmldoifelse{#1}{./attribute('num')}{yes}{no},
ownnumber=\xmldoifelse{#1}{./attribute('num')}{\xmlatt{#1}{num}}{}
\stopxmlsetups
\startxmlsetups xml:chapter
\startchapter[
\xmlcommand{#1}{.}{xml:fillTitleAtts}
]
\xmlflush{#1}
\stopchapter
\stopxmlsetups
which would be nicely reusable but that attempt failed whith the same
error message - thus I thought they are related.
I have to mention, that I try not to process one file but to write
setups for a bunch of similar but slightly different books (we're doing
about 1000 books per year),
so my setups have to be clearly structured and easyly adaptable to
different needs.
I dunno if that can clear up things, if not, I think its not worth much
more discussion.
Thanks,
Achim
