Java XMLUnit comparing XML-files with different information ordering

Question

I am trying to validate and check difference between two XML files.

XML-file 1:

<Customer .....>
    <Description description="Foo" name="Foo" language="svSE"/>
    <Description description="Bar" name="Bar" language="enUS"/>
</Customer>

XML-file 2:

<Customer .....>
    <Description description="Bar" name="Bar" language="enUS"/>
    <Description description="Foo" name="Foo" language="svSe"/>
</Customer>

As you can see the description value is in different order in the two files. But they are still both legit XML-files for import.

When trying to compare them in my Unit-test, i get the following Assertion error:

junit.framework.AssertionFailedError: org.custommonkey.xmlunit.Diff [different] Expected attribute value 'Foo' but was 'Bar' - comparing at /message[1]/Customer[1]/Description[1]/@description to at /message[1]/Customer[1]/Description[1]/@description

Here is the XmlUnit java code:

public class FooTest extends AbstractTest {

    ...

    @Test
    public void assertFooBarFile() {

        ...

        XMLUnit.setIgnoreComments(Boolean.TRUE);
        XMLUnit.setIgnoreWhitespace(Boolean.TRUE);
        XMLUnit.setNormalizeWhitespace(Boolean.TRUE);
        XMLUnit.setIgnoreDiffBetweenTextAndCDATA(Boolean.TRUE);
        XMLUnit.setIgnoreAttributeOrder(Boolean.TRUE);
        XMLAssert.assertXMLEqual(doc1, doc2);
    }
}

Any ideas on how I should compare that the both files contain the same information (without caring in which order the information is generated)?

You can try this.

public static boolean compareXMLs(String xmlSource, String xmlCompareWith)
        throws Exception {
XMLUnit.setIgnoreWhitespace(true);
XMLUnit.setIgnoreComments(true);
XMLUnit.setIgnoreAttributeOrder(true);

XMLUnit.setNormalizeWhitespace(true);

Diff myDiff = new Diff(xmlSource, xmlCompareWith);
myDiff.similar()
}

Test

String x1 = "<a><a1/><b1/></a>";
String x2 = "<a><b1/><a1/></a>";
assertTrue(compareXMLs(x1, x2));

I also have the attributes of the xml-elements to compare against each other, not just the structure – henrik Mar 26 '15 at 11:56

I solved it by adding:

Diff diff = new Diff(doc1, doc2);
diff.overrideElementQualifier(new ElementNameAndAttributeQualifier());
XMLAssert.assertXMLEqual(diff, Boolean.TRUE);
