37 * Transforms a XML element node in a JavaScript object. Attributes defined for
38 * the element will be available as properties, as long as child  element
39 * nodes, but the later will generate arrays with property names prefixed with "$".
40 *
41 * For example, the following XML element:
42 *
43 *		<SomeNode name="Test" key="2">
44 *			<MyChild id="10">
45 *				<OtherLevel name="Level 3" />
46 *			</MyChild>
47 *			<MyChild id="25" />
48 *			<AnotherChild price="499" />
49 *		</SomeNode>
50 *
51 * ... results in the following object:
52 *
53 *		{
54 *			name : "Test",
55 *			key : "2",
56 *			$MyChild :
57 *			[
58 *				{
59 *					id : "10",
60 *					$OtherLevel :
61 *					{
62 *						name : "Level 3"
63 *					}
64 *				},
65 *				{
66 *					id : "25"
67 *				}

69 *			$AnotherChild :
70 *			[
