[NTG-context] Re: xmldoif: checking for contents of attribute
One way would be to do the search in Lua; when you have multiple searches to
perform, that may be the easiest way to go. For example:
\startxmlsetups xml:test
\xmlsetsetup{#1}{*}{-}
\xmlsetsetup{#1}{doc|element}{xml:*}
\stopxmlsetups
\xmlregisterdocumentsetup{test}{xml:test}
\startxmlsetups xml:doc
\xmlflush{#1}
\stopxmlsetups
\startxmlsetups xml:element
\xmlfunction {#1} {element}
\stopxmlsetups
\startluacode
function xml.functions.element (t)
if t.at.class and t.at.class:find ("abc") then
context.startcolor { "blue" }
lxml.flush (t)
context.stopcolor ()
else
context.startcolor { "red" }
lxml.flush (t)
context.stopcolor ()
end
end
\stopluacode
\startbuffer[test]
Yes
No
\stopbuffer
\starttext
\xmlprocessbuffer{test}{test}{}
\stoptext
Hope that gets you started.

It would be a workaround for the sample I submitted, but not for "\xmldoif".

[NTG-context] xmldoif, \startSECTION ... \stopSECTION and \setuphead
Dear list,
I have the following sample:
\setuphead[chapter]
[beforesection=\TeX,
aftersection=\TeX]
\starttext
\startchapter[title=Chapter,
beforesection=\ConTeXt,
aftersection=\ConTeXt]
This is my chapter.
\stopchapter
\stoptext
After checking i-context, the options for the second pair of brackets are:
KEY = VALUE
Well, I think this is the standard case. Aren’t values inherited from
\setuphead? What would be the valid keys for this case?
I need to use \xmldoif in beforesection and aftersection. As far as I
can see, it doesn’t work inside \setuphead.
What would be my approach to deal with "\xmldoif{#1}{.[@id='topic' and
contains(@class,'hidden')]}" in beforesection?
I realize that "\definehead[specialchapter][chapter]" would be a
workaround, but I would like to find a more proper solution.
Many thanks for your help,

The output Euro set! is printed always, it doesn't matter whether I put

Also I can't find any clue on the suggested page 49 of xml-mkiv.pdf

Hi Geert,
the syntax reads \xmldoif{#1}{lpath}{action}. So your conditional may read:
\xmldoif{#1}{currency[first() and contains(text(),'EURO')]}
{Euro set!}
In a complete sample (with dollar set first [it won’t show the result
unless you set EURO first]):
\startbuffer[demo]
DOLLAR
EURO
\stopbuffer
\startxmlsetups xml:initialize
\xmlsetsetup{#1}{doc}{xml:*}

{Euro set!}
\stopxmlsetups
\setuppapersize[A8]
\starttext
\xmlprocessbuffer{main}{demo}{}

It is all in xml-mkiv.pdf

just discovered it .

[NTG-context] XML xmldoif struggle!
Hi,
I've the following XML tag in my XML file:
EURO
.
with invoice being the root tag!
Now I have a setup defined as below (only part!):
\startxmlsetups xml:invoice:invoice
\xmlfirst{#1}{currency} \par
\xmldoif{\xmlfirst{#1}{currency}}{contains(text(),'EURO')} {
Euro set! \par
}
.
The \xmlfirst{#1}{currency} command prints EURO as expected.
But the xmldoif command doesn't cause the Euro set be printed?!
What's wrong here? The manual xml-mkiv.pdf doesn't give me any hint on
how to make this work!
Regards,
Gerard
