XML: mapping definiton on the fly?

XML: mapping definiton on the fly?

[Johannes Graumann]

Dear XML-processing inclined,

I was wondering whether with MarkV it is possible to parse an XML file that
contains style definitions as well as there usage and create context
mappings for them on the fly. In the example fragment below this would
mean:
- scan the file until hitting the "<office:automatic-styles>" tag
- analyze the style definition, find it to be
        of family text
        of name T1
        requiring bold fonts
- construct a context/XML mapping along the lines of
    \startxmlsetups T1
      \bf{\xmlflush{#1}}
    \stopxmlsetups
- keep on scanning, when hitting the style invocation: use the dynamically
generated mapping.

Please excuse the hobbyists nomenclature. Thank you for your time and
insight,

Joh

Hans,

Can you drop any hints as to whether this is even possible and whether
there's something exemplary around I may meditate about?

Thanks, Joh

this kind of questions always puts me in "need to think about it" mode 
which may take some time

anyhow, one solution is ...

\startluacode
   for e, d, t in xml.elements(lxml.id("#1")) do
	tex.sprint(...)	
   end
\stopluacode

of course ... untested

for nicer solutions i need more time

Take all the time you need ... just let me know when the right time comes
for some gentle prodding ... ;0)
I'll go meditate over your hints for a while in the meantime ...

Thank you for the tools!

Joh
