The xml-count() function does not result in 0 when none of the node

In \writestatus{}{<\xmlfilter{#1}{/img/count()}>}
correctly returns: : <1>
But in one would expect the result to be zero but instead
an error occurs: : <>
This is a nuisance because a simple \ifcase .. \or ... \else ... \fi now
fails.
! Missing number, treated as zero.

\@@su:xml:case:frontfigure .../img/count()}\relax
\ifcase
Can this be remedied?
puzzles me as i return 0 in case of nil .. small example needed
