$pngroup is the group you want but
$pmgroup/../../.. is the manufacture element so

$pmgroup/../../../mfg

selects all the mfg children of manufacture.

what you want is the mfg that's the gradparent of teh pmgroup select so
that's

$pmgroup/../..

Or more simply replace

for $pmgroup in
doc("file:example.xml")/pmcatalog/manufacture/mfg/pmdata/pmgroup
where contains($pmgroup/keyword, "pgroup8") 
return $pmgroup/../..

by

doc("file:example.xml")/pmcatalog/manufacture/mfg[contains(pmdata/pmgroup/keyword,"pgroup8")]

The children of a node are an intrinsic property of the node (as is its
parent) if you just want an element node with the same name, but without
the children and parent of the node in the source then you need to
construct a new node, as you observed.
