[NTG-context] Re: attribute selection

30 Aug 2023

      Finally I saw the problem. Calling \xmlfilter{#1}{./node/command(demo:attribute:node)} is the right way.
Sorry for the noise.

This line of code comes from the xml documentation (page 31):
\xmlfilter{#1}{./node[@type=="cleanup"]}
It should select among the <node>'s those with <node type="cleanup">.
However, this node is not selected in the call to \xmlfilter.
Where am I wrong?
MWE follows
% failure to typeset attribute selected.
\setuppapersize[A5][A5]
\startxmlsetups demo:attribute
  \xmlsetsetup{#1}{root|node}{demo:attribute:*}
\stopxmlsetups
\xmlregisterdocumentsetup{demo}{demo:attribute}
\startxmlsetups demo:attribute:root
  Execute \type{\xmlall{#1}{./node}}
