Hi all,
I thought I had done this and it was easy, but I can't
find a solution: I want to test whether a xml tag has an
attribute and vary the typeset content accordingly. There
used to be \xmldoifelseempty, but that has been commented
out (lxml-ini.mkiv). What else could I use? Here's a small
test that shows what I'm trying to do:
\startbuffer[test]
<a>
<b>some text</b>
<b important="different">more text</b>
</a>
\stopbuffer
\startxmlsetups xml:testsetups
\xmlsetsetup{\xmldocument}{a|b}{xml:*}
\stopxmlsetups
\xmlregistersetup{xml:testsetups}
\startxmlsetups xml:a
\xmlflush{#1}
\stopxmlsetups
\startxmlsetups xml:b
\xmldoifelse{#1}{./[...@important]}
%\doifemptyelse{\expanded{\xmlatt{#1}{important}}}
{\color[darkred]{NOTEMPTY: \xmlatt{#1}{important}}\par}
{\color[darkblue]{EMPTY: \xmlflush{#1}\par}}
\stopxmlsetups
\starttext
\xmlprocessbuffer{main}{test}{}
\stoptext
Hints appreciated!
All best
Thomas
