[NTG-context] attribute selection

30 Aug 2023


      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.
