Hi,
I'm typesetting an XML document where the links to the images contain spaces which are encoded as %20
<graphic xlink:href="a%20filename%20with%20spaces.jpg"/>
Using this works in cases without spaces:
\startxmlsetups xml:fig:graphic
\externalfigure[\xmlatt{#1}{xlink:href}]
\stopxmlsetups
This also works for normal spaces, but is there a way to decode/expand the %20s to regular spaces?
I've tried with some Lua, but I don't really know how to pass data around.
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\startluacode
function replaceSpaces(s)
result = string.gsub(s, "%%20", " ")
context(result)
end
\stopluacode
\define[1]\replaceSpaces{\ctxlua{replaceSpaces("#1")}}
\startxmlsetups xml:fig:graphic
\externalfigure[\replaceSpaces{\xmlatt{#1}{xlink:href}}]
\stopxmlsetups
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
Any hints, why this does not work?`
Also, maybe there's a simpler way for this kind of scenario?
Best,
Denis

I'm thinking that it has something to do with the percent characters... This here works just fine: \startluacode function test(s) result = string.gsub(s, 'x20', 'MATCH') context(result) end \stopluacode \define[1]\test{\ctxlua{test("#1")}} \starttext \test{asdfx20} % -> asdfMATCH \stoptext But this here won't: \startluacode function test(s) result = string.gsub(s, '%%20', 'MATCH') context(result) end \stopluacode \define[1]\test{\ctxlua{test("#1")}} \starttext \test{asdf%20} % -> does not work \stoptext Any ideas?
