Jon,
OK, good to know. I'll need a bit more leisure to look at
your example; here are just a few points:
processing an attribute with the 'xml:' namespace has been
fixed by Hans very recently (last weekend), so if you
haven't updated to the latest beta version, please do and
try again; your syntax \xmlsetsetup{#1}{div[@xml:id='a']}
is basically right.
Addressing content that has been set in xml anchors is
possible, but not quite easy. I wouldn't have been able to
figure it out without Hans. Just to show you an example:
here's code that in my TEI document will fetch the content
of a witness list:
\xmlfirst{#1}{root::/TEI/text/front/div[@type=='sigla']/listWit/witness[@xml:id==string.sub('\xmlatt{#1}{wit}',2)]}
The (for you) relevant part is "root::/": this is the
topmost level of your TEI xml document. You then traverse
all the elements and drill down to a <witness> element
whose xml:id attribute is identical to the "wit" attribute
of your current element. So <element wit="#foo"> will pick
up the content of <witness xml:id="foo">bar</witness> and
print "bar." This should get you going.
Last point: I don't want to sound negative, but what
you're attempting is not straightforward and certainly not
easy stuff. I am currently planning on doing a long-term
project on editing texts in this manner, and I'm quite
optimistic that all problems can eventually be solved. But
if you need short-term solutions, a perfectly typeset
edition within a matter of weeks, this may not be possible
right away. E.g., I don't think we really have a solid
framework yet for a bilingual edition as you envisage it.
It is possible, but not easy, Hans needs the time and many
test cases to make the code work. There is a research
group here in Germany (with public funding) who are
currently working on xml printing of material of exactly
this type. I can assure you that for the time being,
there's nothing out there which comes even close to
ConTeXt in this area, but we're still at the beginning.
So: if you want to help and test and be part of this, you
are more than welcome, but none of us has a magic bullet;
this is work in progress, not drop-in solutions.
All best
Thomas
