If you are you trying to to test your custom implementation of
DifferenceListener, this is a problem, I agree.

What I suggested was that you write a DifferenceListener like
(untested code, I didn't try to even compile it):

public class MyDiffListener implements DifferenceListener {

    public int differenceFound(Difference d) {
        if (d.getId() == DifferenceConstants.ELEMENT_TAG_NAME_ID
            && d.getControlNodeDetail().getValue().equals("foo")
            && d.getTestNodeDetail().getValue().equals("bar")) {
            return RETURN_IGNORE_DIFFERENCE_NODES_IDENTICAL;
        }
        return RETURN_ACCEPT_DIFFERENCE;
    }

    public void skippedComparison(Node control, Node test) {}
}

and use Diff.overrideDifferenceListener() with an instance of your
class.

I know you cannot write tests for MyDiffListener, but it is pretty
easy to validate and using the approach outlined above, your XMLUnit
tests should skip over differences between "foo" and "bar" nodes.
