i run a query and all i get is the listing of command line params and some example xsl, exactly what calling xmlstarlet without any paramters produces.
i deduce, that some kind of error occured or xmlstarlet choked on a namespace definition which i just added -- but that's pure conjecture.
instead of the rather lengthy and in this case confusing listing of parameters and xsl example code a meaningful messages is necessary.

Please, could you attach the exact command you run (and xml files, if it
is necessary) to be able to reproduce the problem?

Thanks.
