XML : Querying XML with Java

I'm able to run simple queries on my XML document using Java, but I'm looking to run a more 'advanced' query and have run into a bit of trouble in doing so.

I am able to get the name of only the first actor of this example (in this case Marlon Brando), when I want to get the names of the rest of the actors in the XML file.

I have used so far /film/cast which shows me all of the actor names, but also the role they play within the film; which I do not want.

Please help! Thanks

XMl:

      <!--?xml version="1.0"?-->  <film>      <title>"Godfather, The"</title>      <year>1972</year>      <directors>          <director>Francis Ford Coppola</director>      </directors>      <genres>          <genre>Crime</genre>          <genre>Drama</genre>      </genres>      <plot>Son of a mafia boss takes over when his father is critically wounded in a mob hit.</plot>      <cast>          <performer>              <actor>Marlon Brando</actor>              <role>Don Vito Corleone</role>          </performer>          <performer>              <actor>Al Pacino</actor>              <role>Michael Corleone</role>          </performer>          <performer>              <actor>Diane Keaton</actor>              <role>Kay Adams Corleone</role>          </performer>          <performer>              <actor>Robert Duvall</actor>              <role>Tom Hagen</role>          </performer>          <performer>              <actor>James Caan</actor>              <role>Sonny Corleone</role>          </performer>      </cast>  </film>
