Hi,
I have the following xml setup with a lua function:
\startluacode
function markingLength(s)
_,n = s:gsub("%S+","")
if n > 3 then
context("yes" .. " ...") else context("no") end
end
\stopluacode
\startxmlsetups xml:ink:ink-title:marking
%\ctxlua{markingLength(\xmlflush{#1})} % does not work
\ctxlua{markingLength{"1 2 3 4"}}
\stopxmlsetups
While the function works, I cannot use xmlflush here. How can I properly pass the xml content to the lua function?
Best,
Denis

Note: you may need to strip some XML tags from that content. If the element is not straight-up data but has nested elements, then this will return the full xml representation instead: <title>A short title</title> => ‘A short title' <title><A short title></title> => ‘<A short title>' <title><A <b>short</b> title></title> => '<title><A <b>short</b> title></title>' Best wishes, Taco > On 12 Sep 2023, at 08:56, <denis.maier@unibe.ch> <denis.maier@unibe.ch> wrote: > > Ok, I’ve found a way, see below. > But maybe someone has some nice lua (or other) tricks to share… (I’m not sure accessing t.dt[1] is particularly safe when operating on nested structures.) > Best, > Denis > \startbuffer[test] > <?xml version="1.0" encoding="UTF-8"?> > <doc> > <chapter> > <title>A short title</title> > <p>asdf asdf asdf jklö jklö jklö</p> > </chapter> > <chapter> > <title>A longer title bla bla bla bla bla bla bla bla</title> > <p> > asdf asdf asdf jklö jklö jklö > </p> > </chapter> > </doc> > \stopbuffer > \startxmlsetups xml:test > \xmlsetsetup{#1}{*}{-} > \xmlsetsetup{#1}{doc|chapter|p}{xml:*} > \stopxmlsetups > \xmlregisterdocumentsetup{test}{xml:test} > \startxmlsetups xml:doc > \xmlflush{#1} > \stopxmlsetups > \setuphead[chapter][expansion=yes] % make sure the stuff gets expanded on time > \startxmlsetups xml:chapter > \startchapter > [ > title={\xmlfilter{#1}{/title/command(xml:chapter:title)}}, > marking={\xmlfilter{#1}{/title/command(xml:chapter:title:marking)}}, > ] > \xmlflush{#1} > \stopchapter > \stopxmlsetups > \startxmlsetups xml:p > \xmlflush{#1}\par > \stopxmlsetups > \startluacode > function xml.functions.getMarking(t) > _,n = t.dt[1]:gsub("%S+","") > if n > 10 then local words = {} for word in t.dt[1]:gmatch("%S+") do table.insert(words, word) end > local resWords = {} > resWords = { unpack( words, 1, 7 ) } > res = table.concat(resWords, " ") ..
