XMLUnit comparison is not working if namespace details are included in the root element

[sureshthota]

I am trying to compare two XMLs which has the same data but in different order. When root element has no namespace and other attributes the comparison works fine. It says both are identical. However when I include namespace details it is complaining about the elements which are not in order. Please note that I tried to downgrade all the relevant differences. But it did not work.

Below are code and XML details along with the error.

XML 1:

<root xmlns:core="http://www.testeng.test.com/core"
  xmlns="http://www.company.test.com/schemas/atlas"

          <Value3 Key="3">Example3</Value3>
        </Keys>

        <Keys>
          <Value1 Key="1">Example5</Value1>
          <Value2 Key="2">Example8</Value2>
          <Value3 Key="3">Example6</Value3>
        </Keys>
      </B1>
    </A1>
</root>

Code:

public class CompareXmls {


    public static void main(String[] args) {
        DifferenceEvaluator evaluator = DifferenceEvaluators.chain(DifferenceEvaluators.Default, new MyEvaluator(),
            DifferenceEvaluators.downgradeDifferencesToEqual(ComparisonType.CHILD_NODELIST_SEQUENCE),
            DifferenceEvaluators.downgradeDifferencesToEqual(ComparisonType.NAMESPACE_PREFIX),
            DifferenceEvaluators.downgradeDifferencesToEqual(ComparisonType.NO_NAMESPACE_SCHEMA_LOCATION),
            DifferenceEvaluators.downgradeDifferencesToEqual(ComparisonType.NAMESPACE_URI),
            DifferenceEvaluators.downgradeDifferencesToEqual(ComparisonType.SCHEMA_LOCATION),
            DifferenceEvaluators.downgradeDifferencesToEqual(ComparisonType.DOCTYPE_NAME),
            DifferenceEvaluators.downgradeDifferencesToEqual(ComparisonType.DOCTYPE_PUBLIC_ID),
            DifferenceEvaluators.downgradeDifferencesToEqual(ComparisonType.DOCTYPE_SYSTEM_ID));

        InputStream resourceAsStream1 = TestXmlComparison.class.getClassLoader().getResourceAsStream("X1.xml");
        InputStream resourceAsStream2 = TestXmlComparison.class.getClassLoader().getResourceAsStream("X2.xml");

        Diff diff = DiffBuilder.compare(Input.from(resourceAsStream1))
            .withTest(Input.from(resourceAsStream2))
            .ignoreComments()
            .ignoreWhitespace()
            .normalizeWhitespace()
            .checkForSimilar()
            .withDifferenceEvaluator(evaluator)
            .withNodeMatcher(new DefaultNodeMatcher(ElementSelectors.conditionalBuilder()
                .whenElementIsNamed("Keys")
                .thenUse(ElementSelectors.byXPath("./Value1", ElementSelectors.byNameAndText))
                .elseUse(ElementSelectors.byName)
                .build()
             )).build()
            ;
        System.err.println(diff);
    }
}

Error/Differences:

Expected text value 'Example1' but was 'Example5' - comparing <Value1 ...>Example1</Value1> at /root[1]/A1[1]/B1[1]/Keys[1]/Value1[1]/text()[1] to <Value1 ...>Example5</Value1> at /root[1]/A1[1]/B1[1]/Keys[1]/Value1[1]/text()[1]

As I mentioned earlier, If I just use <root> with out namespace details I am getting response as Identical.

Please help.

The wonders of using XPath and namespaces are with no end :-)

XPaths do require a NamespaceContext if you use any namespaces in your document.

If you throw in

        Map<String, String> m = Collections.singletonMap("foo", "http://www.company.test.com/schemas/atlas");

and use

.thenUse(ElementSelectors.byXPath("./foo:Value1", m, ElementSelectors.byNameAndText))

things work as they do without any namespaces.
