Hello,

I’m trying to build an xmlsetsetup with an own lua function. XML in MKIV says on pg. 33:

You can also use normal Lua functions as long as you make sure that you pass the right arguments.

There are a few predefined variables available inside such functions.

list table the list of matches

l number the current index in the list of matches

ll element the current element that matched

order number the position of the root of the path

But I can’t figure out how to get access to list, ll etc.

My MWE (only for testing the access, is always true):

\startbuffer[text]

<para>Dies ist <inline style="sup">ein</inline> xxx<inline style="sub">zwei</inline> noch ein <inline style="sup">sup</inline> Test<inline style="sub">sub</inline></para>

\stopbuffer

%\enabletrackers[xml.parse,xml.path]

\startluacode

  function xml.expressions.nextnodeatt(e)

                inspect(e)

                inspect(ll)

                return('sub')

  end

\stopluacode

\startxmlsetups xml:textsetups

    \xmlsetsetup{#1}{*}{+}

    \xmlsetsetup{#1}{para}{xml:*}

    \xmlsetsetup{#1}{inline[@style='sup'][xml.expressions.nextnodeatt(ll)=='sub']}{xml:sub}

\stopxmlsetups

\xmlregistersetup{xml:textsetups}

\startxmlsetups xml:para

    \xmlflush{#1}\par

\stopxmlsetups

\startxmlsetups xml:sub

    \color[red]{\xmlflush{#1}}

\stopxmlsetups

\starttext

    \xmlprocessbuffer{main}{text}{}

\stoptext

Thanks in advance,

Achim
