  Confirmed, the nodeset is one part of the full object. Just free
the XPath returned object.
  You don't have to free the nodes pointed (but you will have to free
the document at the end of processing). In general the nodeset just
points to nodes in the document (small exception is namespace nodes
but that's taken care by freeing the object).
