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.xml.sax.SAXException;

	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
	{

		/*

		 * @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;
		}


		/*

		@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);
	}
}
