You are not subscribed to the list so your mails end up in the
moderation queue and I simply didn't recognize it between all the SPAM
that the list receives (about one legitimate email is hidden between
several hundred SPAM messages, the list receives about ten SPAM messages
each day).

That's what we are here for. 8-)

OK, let me see.  You expect documents like

<container>
  <POI ...>
    <some-element-name>ID1</some-element-name>
  </POI>
  <POI ...>
    <some-element-name>ID2</some-element-name>
  </POI>
</container>

and want to compare elements with matching IDs, right?  In general I'd
expect RecursiveElementNameAndTextQualifier to work here, so I may be
missing a detail.

Your code assumes that calling getChildNodes().item(0) on a POI element
will return the Node corresponding to the element some-element-name - is
this true?  In my snippet above you'd likely first get a Text child node
containing a linebreak and four spaces.  You probably should make
XMLUnit and your ElementQualifier ignore whitespace.

Can you provide example snippets of real XML documents you are trying to
compare?
