Fair enough, although I don't have an association JS <-> browser ingrained so much - for me, JS is a general purpose language which happens to be embedded in browsers, but also many other places. Most of my JS code runs either on a server (backend code) or in a development environment (various, let's call it, DevOps-ish scripts). Only now and then I write JS for browsers, and then it is often crippled JS, full of things like "var" (because old browsers etc.) It is one of the puzzling areas to me: no problem in browsers and elsewhere but not in open source pdf viewers. It's not the most complex stuff so it probably indicates that no one cares much about these features. >>> >>> I wouldn’t say "no problem", because JS causes security problems everywhere. >> >> It's not JS that causes problems.

Hi,
Thomas, thanks a lot, and it is fairly simple if you know how to read
the following (taken from page 22, chapter 3.6):
\xmlattribute {...} {...} {...}
finds a first match for LPATH at NODE and returns the value of attribute

But now I get it, thanks!

[NTG-context] How to get attribute value from xml tag?
Hi,
Struggling with XML in ConTeXt.
I'have the following tag in my xml file:
...
20
...
\startxmlsetups xml:invoice:travel
\xmlfirst{#1}{distance}
\stopxmlsetups
The \xmlfirst{#1}{distance} yields /20/, but how can the unit attribute
value /km/ be accessed?

When splitting extreme tables, I cannot use \dontleavehmode.
1. What is the purpose of \dontleavehmode in your example?
Sorry, Wolfgang, I forgot to mention.
\dontleavehmode is required to center the table when
\startmakeup[standard][align=center].
You can use the float environment and disable the counter.
\starttext
\startplacefigure [location={none,split}]
\startxtable
\dorecurse{100}
{\startxrow
\startxcell xxx \stopxcell
\startxcell xxx \stopxcell
\stopxrow}
\stopxtable
\stopplacefigure
\stoptext
Another option is framedtext which can be centered.
\starttext
\startframedtext [location=middle,width=fit,frame=off]
\startxtable
\startxrow
\startxcell xxx \stopxcell
\startxcell xxx \stopxcell
\stopxrow
\stopxtable
\stopframedtext
\stoptext
2. Why do you try to split a table in a makup environment (which will
never work)?
\setupxtable[split=yes] is a general setup for the whole document.
I mean, I don’t want a table in the document to be stuck between pages.
Only sometimes I have makeups with tables. And this was my first issue
with the conflicting general setup.
When you short table keeping them together can be better or do you want
short tables with five rows to be split across pages.

When splitting extreme tables, I cannot use \dontleavehmode.
1. What is the purpose of \dontleavehmode in your example?
2. Why do you try to split a table in a makup environment (which will
never work)?
Since this worked before, am I missing something or is this a bug?
It isn't a bug but a side effect of the way how split=yes works.
The normal splitters uses a simple placement method where each table row
is placed below each other. To prevent unwanted white space between the
lines \nointerlineskip is used but the command works only a vertical
mode. With \dontleavehmode like in your example you force horizontal
mode for the table which results in the error message.
You can reproduce the error with the following minimal example:
\starttext
\dontleavehmode
\vbox{}
\nointerlineskip
\vbox{}
\stoptext
The reason why this doens't happen when splitting is disabled or when
the header or footer lines are repeated is that ConTeXt puts the
collected lines for each table in a \vbox. When you flush the lines in
the \vbox the are placed in vertical modes and your \dontleavehmode is
only applied to the outer \vbox while the lines itself are placed in
vertical mode.
\starttext
\dontleavehmode
\vbox
{\vbox{}
\nointerlineskip
\vbox{}}
\stoptext
