Hi all,

I'm terribly sorry I have to send three files for this test case, but I'm trying to process xml with lua, so it's difficult to do otherwise. I have two problems:

1. (probably unrelated to xml/lua): when I try to set the options (l. 22-3 in test-style.tex)

\setupxtable [split=yes, spaceinbetween=medium]

for the xtable environment, I get an error:

tex error > error on line 22 in file /mnt/shared/context/tex/texmf-context/tex/context/base/cont-yes.mkiv: ! You can't use `\prevdepth' in horizontal mode

\nointerlineskip ^^@-\prevdepth -\thousandpoint l.22 \nointerlineskip

\ctxcommand #1o-\directlua {commands.#1}

\tabl_x_process ...lse \tabl_x_flush_text_checked \fi \fi \ctxcommand {x_tab... l.8 }

\ctxlxml #1h-\ctxlua {lxml.#1}

.... l.91 \stopluacode

This looks like a buglet in xtables to me.

2. I would like to test whether a certain element has already been seen (l. 8-13 in test-style.lua). However, since tables are two-pass, the test will always return "true." How could I test properly?

many ways ... (ok, i might provide some hook into tables) ... three attached i bet you'll choose the third solution Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
