The XMLStreamReader.next method loads the properties of the next event in the stream. You can then access those properties by calling the XMLStreamReader.getLocalName and XMLStreamReader.getText methods.
When the XMLStreamReader cursor is over a StartElement event, it reads the name and any attributes for the event, including the namespace. All attributes for an event can be accessed using an index value, and can also be looked up by namespace URI and local name. Note, however, that only the namespaces declared on the current StartEvent are available; previously declared namespaces are not maintained, and redeclared namespaces are not removed.
