Hello Nico and Nick,
Hmmm, this doesn't seem to be quite well behavior of the
HippoSimpleXMLExtractor, but changing it might influence other projects
using this behavior.
I once though added for a client a version of a jar (from top of my head
do not remember whether you can configure this now, but if needed I
could sort it out) that deletes an empty property entirely. That would
in the end result in the desired behavior for you.
Adding you own extractor though shouldn't be very hard,
Regards Ard
