Hi,
I'm trying to check whether an attribute contains (or, actually starts with) a given string.
I've tried a whole bunch of different combinations, but I've had no luck so far. Minimal example below. Anyone has a hint?
Best,
Denis

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]
<?xml version="1.0" encoding="UTF-8"?>
<doc>
<element class="abcdefg">Yes</element>
<element>No</element>
</doc>
\stopbuffer
\starttext
\xmlprocessbuffer{test}{test}{}
\stoptext
Hope that gets you started.

Thank you, Thomas. Yes, that get's me started. But same question applies this solution too: Why do you need to double check? (I guess the answer will probably be the same.)
Anyway, it looks like I should really look more into Lua as this will probably make a few things much easier.
Best,
Denis

Thanks for your help. I can use that, but why is this sort of double-checking necessary here?
\startxmlsetups xml:test
\xmlsetsetup{#1}{*}{-}
\xmlsetsetup{#1}{doc|element}{xml:*}
\stopxmlsetups
\xmlregisterdocumentsetup{test}{xml:test}
\startxmlsetups xml:doc
\xmlflush{#1}
\stopxmlsetups
\startxmlsetups xml:element
1 \xmldoifelse{#1}{.[@class and contains(@class,'abc')]}{Yes}{No} \par
2 \xmldoifelse{#1}{.[@class and find(@class,"abc")]}{Yes}{No} \par
3 \xmldoifelse{#1}{.[True and contains(@class,'abc')]}{Yes}{No} \par % runs, but no match
4 \xmldoifelse{#1}{.[True and find(@class,"abc")]}{Yes}{No} \par % run, but no match
% 5 \xmldoifelse{#1}{.[contains(@class,'abc')]}{Yes}{No} \par % causes an error
% 6 \xmldoifelse{#1}{.[find(@class,"abc")]}{Yes}{No} \par % causes an error
\stopxmlsetups
\startxmlsetups xml:whatever
Yes
\stopxmlsetups
\startbuffer[test]

because containsa in a function that has checking while find is just the
lua find .. so i've added a check in that one too now but no upload

So, that would mean that the double checking is only necessary for find, not for contains. And indeed the example below works.
Is that correct or are there any unwanted side-effects?
\startxmlsetups xml:test
\xmlsetsetup{#1}{*}{-}
\xmlsetsetup{#1}{doc|element}{xml:*}
\stopxmlsetups
\xmlregisterdocumentsetup{test}{xml:test}
\startxmlsetups xml:doc
\xmlflush{#1}
\stopxmlsetups
\startxmlsetups xml:element
1 \xmldoifelse{#1}{.[contains(@class,'abc')]}{Yes}{No} \par
2 \xmldoifelse{#1}{.[@class and find(@class,'abc')]}{Yes}{No} \par % runs, but no match
\stopxmlsetups
\startxmlsetups xml:whatever
Yes
\stopxmlsetups
\startbuffer[test]
<?xml version="1.0" encoding="UTF-8"?>
<doc>
<element class="abcdefg">Yes</element>
<element>No</element>
</doc>
