Here is the beginning of an answer :

This can be achieved using
(select-elements (descendants (current-node)) '("PH" "WERK"))
which returns a node-list comprising elements in the subtree with WERK as
gi and whose parent's gi is PH.
See the specification 
  10.2.5. SGML Property Operations

For this, I should compare each node in the the node list with the
following ones and copy it to a second list if there is no match. But
there may be other (and probably better) methods.

I don't know.

Hope it helps.
