XMLUnit ignore Order of Elements

Question

I compare two xml files with each other with the help of XMLUnit now if i use this code to compare

@Test
public void testForEquality() throws Exception {
 String xml1 = "<table = "01"><uid></uid></table><table = "02"><uid></uid></table>";
 String xml2 = "<table = "02"><uid></uid></table><table = "01"><uid></uid></table>";
 assertXMLEqual(myControlXML, myTestXML);
 Diff diff = new Diff(myControlXML, myTestXML);
 assertTrue(diff.similar());
}

now it gives me out: Expected attribute value '02' but was '01' but i don't want a difference i want the table id to be unique and only check what the Main-Element in this case:table -> contains if the same table id is seen in the other file.

i allready lookt through simmilar questions but they did not helped me out.

You need to tell XMLUnit which rules to apply to identify the table elements it should match with each other. You do so by configuring an ElementQualifier - in your case you will want to use the built-in ElementNameAndAttributeQualifier passing the identifying attribute's name as constructor argument.
