XML Unit showing similar XML as false

Question

    XML1:
    <record>
        <record name="technicalEnvelope" javaclass="XXX">
          <value name="flowReferenceId">xyz</value>
        </record>
        <record name="functionalEnvelope" javaclass="XXX">
          <value name="flowReferenceId">abc</value>
        </record>
    </record>
    XML2:
    <record>
        <record name="functionalEnvelope" javaclass="XXX">
          <value name="flowReferenceId">abc</value>
        </record>
        <record name="technicalEnvelope" javaclass="XXX">
          <value name="flowReferenceId">xyz</value>
        </record>
    </record>

    Diff myDiff = new Diff(XML1, XML2);
    assertTrue("pieces of XML are similar " + myDiff, myDiff.similar());

Comparison fails for these two similar XML due to different order. Any help/guidance would he highly appreciated.

Thanks Rao for your comment but sorting will not help me here as one xml gets generated at runtime which is being compared with expected xml. — Hoshang, Jan 27 '15 at 10:25
Had similar problem some time ago, so what i did was pass the runtime generated file and static file to a program which did the sorting, then pass that out put another utility like xmlunit for comparison. But that was for a specific type of xml, not for generic xml. — Rao, Jan 27 '15 at 10:39
Thanks Rao ... I found a solution which I have posted below. — Hoshang, Jan 27 '15 at 10:44

    Diff myDiff = new Diff(myControlXML, myTestXML);
    myDiff.overrideElementQualifier(new ElementNameAndAttributeQualifier());
    assertTrue("pieces of XML are similar " + myDiff, myDiff.similar());

Glad to know. But this may not work if you have more complex elements. – Rao Jan 27 '15 at 14:28

For more complex elements you will need to tell XMLUnit how to identify the elements you want to compare with each other. This is exactly ElementQualifier's job. There are a bunch of built-in implementations of ElementQualifier (like ElementNameAndAttributeQualifier used by Hoshang) but if neither of them fits your requirements, you'll need to implement the interface yourself.
