Return the prefix name of the current node if the correct node has a prefix name and NULL otherwise. The returned pointer is owned by this object and must not be modified or deallocated by the caller. The returned pointer becomes invalid upon the next `advanceToNextNode`, when `close` is called or the reader is destroyed.
