Hello, a slightly modified example:
---- t.xml
<a>
<aa number="111">AA</aa>
<ab number="222">AB</ab>
</a>
----
and the Ctx source:
---- t.mkiv
\startxmlsetups xml:T
\xmlfunction{#1}{test}
\xmlsetsetup{\xmldocument}{*}{+}
% \xmlsetsetup{\xmldocument}{*}{-} % Empties output?!
\xmlsetsetup{\xmldocument}{a/aa}{xml:*}
\xmlsetsetup{\xmldocument}{a/ab}{xml:*}
\stopxmlsetups
\startluacode
local aux = aux; if not aux then aux = {}; _G.aux = aux end
xml.functions.aa = function(t)
aux.num = t.at.number
end
\stopluacode
\startxmlsetups xml:aa
\xmlfunction{#1}{aa}
\stopxmlsetups
\startxmlsetups xml:ab
\xmlfunction{#1}{ab}
\ctxlua{context.section("New section " .. (aux.num or "??"))}
\xmlflush{#1}
\stopxmlsetups
\xmlregistersetup{xml:T}
\starttext
Hello
\xmlprocessfile{id}{t.xml}{}
\stoptext
----
Two (remaining) questions:
1)
Why the line "\xmlsetsetup{\xmldocument}{*}{-}" (try to uncomment!) causes the whole
output is empty, even if I specify another operation for "a/ab" elements later?
My intention is to have "{*}{-}" (don't flush anything by default), excluding elements
specified later, e.g. "a/ab" (with another operation specified);
how to achieve this?
2)
How to get "aa.number" from within "ab" element?
I believed "\xmlatt{#1/../aa}{number}" within "a/ab" will do that, but...? How
to do that?
I have a partial solution: when processing "a/aa", I save an attribute value to
a Lua variable, which I use later;
but this solution doesn't look very "clean" for me;
I'd rather find a way to access parental (first) child attributes form within a
node...
Thank you in advance;
I'm not very familiar with Ctx XML processing (so far)...
Best regards,
Lukas
