For many use cases node order is not so significant and so XMLUnit
compares elements out of order if necessary.  For Diff you can solve
that by overriding the DifferenceListener with one that upgrades
CHILD_NODELIST_SEQUENCE differences to non-recoverable.  This will make
Diff stop once it detects elements out of order - it won't help with
DetailedDiff.

Make sure you set the compareUnmatched parameter to false.

The problem here is that XMLUnit 1.x will always attempt to match nodes
regardless of order.  If you set ElementQualifier to null it should
visit elements in correct order, unless there are other node types (like
emoty text nodes) between them that throws its comparison algorithm out
of step.

Can you provide two example documents and say what you'd expect XMLUnit
to return so we have something more concrete to talk about?
