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

Here in Terminal on my Mac:
21 ~: lua
Lua 5.4.6 Copyright (C) 1994-2023 Lua.org, PUC-Rio
> string.gsub('a%20b', '%%20', ' ')
a b 1
> (string.gsub('a%20b', '%%20', ' '))
a b
> ^D
21 ~:
The first call returns the 1 giving the match, the extra ()'s get rid of that second return value.
yours sincerely

Thanks, but I'm still getting the same error. 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?
Best,
Denis
