Summary: Error for xmls with different child & attr sequence

Initial Comment:
I have two xmls

XML 1
<root>
<Override ContentType="slideLayout+xml" PartName="slideLayout1.xml" /> 
<Override ContentType="slideLayout+xml" PartName="slideLayout8.xml" /> 
<Override ContentType="slideLayout+xml" PartName="slideLayout7.xml" /> 
</root>

XML 2
<root>
<Override ContentType="slideLayout+xml" PartName="slideLayout8.xml" /> 
<Override ContentType="slideLayout+xml" PartName="slideLayout1.xml" /> 
<Override ContentType="slideLayout+xml" PartName="slideLayout7.xml" /> 
</root>

XML 3
<root>
<Override PartName="slideLayout8.xml"  ContentType="slideLayout+xml" /> 
<Override PartName="slideLayout1.xml"  ContentType="slideLayout+xml"  /> 
<Override PartName="slideLayout7.xml"  ContentType="slideLayout+xml" /> 
</root>

Accordingly to me all the xmls are equal. I tried using TestCase.java (attached here) to compare them. 

I tried to compare these two xmls ignoring both the child sequence as well as the attribute sequence, but xml unit still complains they are different.

Here is the source code I tried, please let me know what changes do I do my source in order to make XMLUnit say the three xml files are equal.

import java.io.IOException;
import java.util.List;

import org.custommonkey.xmlunit.DetailedDiff;
import org.custommonkey.xmlunit.Difference;
import org.custommonkey.xmlunit.DifferenceConstants;
import org.custommonkey.xmlunit.DifferenceListener;
import org.custommonkey.xmlunit.XMLTestCase;
import org.w3c.dom.Node;
import org.xml.sax.SAXException;

/**

public class TestCase extends XMLTestCase
{
	public static final String TAB = "    ";

	private static final String leftSnippet = "<root><Override ContentType=\"slideLayout+xml\" PartName=\"slideLayout1.xml\" /> <Override ContentType=\"slideLayout+xml\" PartName=\"slideLayout8.xml\" /> <Override ContentType=\"slideLayout+xml\" PartName=\"slideLayout7.xml\" /> </root>";
	private static final String rightSnippet = "<root><Override ContentType=\"slideLayout+xml\" PartName=\"slideLayout8.xml\" /> <Override ContentType=\"slideLayout+xml\" PartName=\"slideLayout1.xml\" /> <Override ContentType=\"slideLayout+xml\" PartName=\"slideLayout7.xml\" /> </root>";


	public void compareString(final String leftContent, final String rightContent) throws SAXException, IOException
	{

		final DetailedDiff myDiff = new DetailedDiff(compareXML(leftContent, rightContent));
		myDiff.overrideDifferenceListener(new NoSequenceDifferenceListener());
		final List<Difference> allDifferences = myDiff.getAllDifferences();
		if ( (null == allDifferences) || (allDifferences.size() <= 0) )
		{
			System.out.println(TAB + "No Difference found");
		}
		else
		{
			System.out.println(TAB + allDifferences.size() + " number of difference found");
		}
		int index = 0;
		for ( final Difference diff : allDifferences )
		{
			System.out.println(TAB + ":" + (index++) + ":  Difference = " + diff);
		}
		System.out.println("=======================================================");
	}

	private class NoSequenceDifferenceListener implements DifferenceListener
	{

		/*
		 * (non-Javadoc)
		 * @see org.custommonkey.xmlunit.DifferenceListener#differenceFound(org.custommonkey.xmlunit.Difference)
		 */
		@Override
		public int differenceFound(final Difference diff)
		{
			int returnVal = DifferenceListener.RETURN_UPGRADE_DIFFERENCE_NODES_DIFFERENT;
			switch ( diff.getId() )
			{
				case DifferenceConstants.ATTR_SEQUENCE_ID:
				case DifferenceConstants.CHILD_NODELIST_SEQUENCE_ID:
					returnVal = DifferenceListener.RETURN_IGNORE_DIFFERENCE_NODES_IDENTICAL;
					break;
				default:
					returnVal = DifferenceListener.RETURN_UPGRADE_DIFFERENCE_NODES_DIFFERENT;
			}
			return returnVal;
		}


		/*
		 * (non-Javadoc)
		 * @see org.custommonkey.xmlunit.DifferenceListener#skippedComparison(org.w3c.dom.Node, org.w3c.dom.Node)
		 */
		@Override
		public void skippedComparison(final Node node1, final Node node2)
		{
			System.out.println("---> node1 " + node1.getLocalName());

		}

	}


	public static void main(final String[] args) throws SAXException, IOException
	{
		final TestCase testcase = new TestCase();
		testcase.compareString(leftSnippet, rightSnippet);
	}
}

Message:
Your problem is not related to attribute order at all, XMLUnit is just not
comparing the elements you want it to compare,

Dy default it will match XML elements by their name and since in your case
all elements have the same name it will compare them in order.  What you
want is to tell XMLUnit it should only compare the elements that have the
same name and the same PartName attribute.  To do so, you'd use an
ElementNameAndAttributeQualifier - see
http://xmlunit.sourceforge.net/userguide/html/ar01s03.html#ElementNameAndAttributeQualifier
