Query returns no results in xQuery : I tried to query an XML file with xQuery in BaseX. Unfortunately the query returns no results. I think this is caused by incorrect declarations of the namespaces in xQuery's prolog. Please see the code below for the namespaces used in the original XML.

Can somebody please tell me which statements I should use to list all product titles (< dcterms:title>)?
