[flexcoders] Testing for XML equality

[Davis Ford]

Why does this test fail?  Is there any way to test for equality that ignores
the ordering of elements -- which shouldn't technically matter?

[Test]
public function testXmlEquality():void {
         var xml1:XML =
         <a>
         <b></b>
         <c></c>
         </a>;
         var xml2:XML =
         <a>
         <c></c>
         <b></b>
         </a>;
         Assert.assertTrue(xml1 == xml2);
        }
