Estoy usando XMLUnit2 para comparar 2 XML que no tienen elementos en el mismo orden. Estoy viendo el siguiente error:

Diferencias = Se esperaba 'billingCode' secundario pero era 'nulo' - comparando en / translateServiceRequestResponse [1] / translateServiceRequestReturn [1] / legacyCode [2] / billingCode [1] a NULL

Código

Diff myDiff = DiffBuilder.compare(controlResponse).ignoreWhitespace().ignoreComments().withTest(testResponse).withNodeMatcher(new DefaultNodeMatcher(ElementSelectors.byNameAndText)).checkForSimilar().build();
System.out.println("Differences = " + myDiff.toString());
