/**
 * Transforms a XML element node in a JavaScript object. Attributes defined for
 * the element will be available as properties, as long as child  element
 * 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",
