Hi,
hope this is comprehensible without a full example: I want to do some
operations on my xml, and that's easier to do in Lua. However, I cannot
find how to filter my results and pass them on to a command. In TeX, I
would do this:
\startxmlsetups xml:a
  \xmlfilter{#1}{/b/command(xml:command:b)}
\stopxmlsetups
\startxmlsetups xml:command:b
  \xmlconcat{#1}{/}\par
\stopxmlsetups
How would I do the same thing in Lua? Here's what I tried:
function xml.functions.a(t)
  local b = lxml.filter(lxml.id(t), "/b")
  process(b)
end
function process(t)
  xml.xprint(t)
end
but that doesn't work yet, I get no results printed. So my question:
what would be the right syntax in Lua? (And bonus points for: what is
the equivalent of \xmlconcat ?)
All best

Replying to myself to correct: should have been

function process(t)
   xml.cprint(t)
end

obviously...
