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

Hans
