Tengo una colección de historias en formato XML. Me gustaría analizar el archivo y devolver cada historia como hash o como objeto Ruby, para poder manipular más los datos dentro de un script Ruby.

HaceNokogiri apoya esto, o hay una mejor herramienta / biblioteca para usar?

El documento XML tiene la siguiente estructura, devuelto a través deAPI web de Pivotal Tracker:
