\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
