I'm not quite sure what you mean by
"aren't you just creating a String?"
The following line:
Object xml = cx.newObject(scope, "XML", new Object []
{"<root-element-of-your-choice/>"});
is intended to create a javascript object of type XML.
ScriptableObject.putProperty(scope, "xml", xml);
places this object in scope.
Object result = cx.evaluateString(scope, "var x =
xml.name();", "<cmd>", 1, null);
is merely intended to show the sort of thing that I might then want to
do with this object inside a script.
