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?
\startluacode
     function xml.finalizers.tex.url(e,a)
         local u = #e > 0 and e[1].at[a]
         local s = u and lpeg.match(lpeg.patterns.urlunescaper,u)
         context(s)
     end
\stopluacode
\startxmlsetups xml:something
     \xmlatt{#1}{xlink:href}\par
     \xmlfilter{#1}{./url('xlink:href')}
\stopxmlsetups

i'll add this
