+ * Transforms a XML element node in a JavaScript object. Attributes defined for

+ * nodes, but the later will generate arrays with property names prefixed with "$".
+ *
+ * For example, the following XML element:
+ *
+ *		<SomeNode name="Test" key="2">
+ *			<MyChild id="10">
+ *				<OtherLevel name="Level 3" />
+ *			</MyChild>
+ *			<MyChild id="25" />
+ *			<AnotherChild price="499" />
+ *		</SomeNode>
+ *
+ * ... results in the following object:

+ *		{
+ *			name : "Test",
+ *			key : "2",
+ *			$MyChild :
+ *			[
+ *				{
+ *					id : "10",
