How do I return a list of values instead of a string when querying a oracle database using XPath?

I am using XPath to query an oracle database where the field I am querying looks like:

<!-- language: lang-xml -->
<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>

I want to return the all the actors who have starred in the film the godfather. At the minute my code looks like:

result = stmt.executeQuery("SELECT a.FILM.extract('/film[title=\"Godfather, The\"]/cast/performer/actor/text()') "
                + "FROM ASS2_Film a "
                + "WHERE a.film.existsNode('/film[title=\"Godfather, The\"]')=1");

System.out.println("\nActor");            

while (result.next()) {   
    System.out.println(result.getString(1)+"\n");
}

At the minute my code is returning:

Actor
Marlon BrandoAl PacinoDiane KeatonRobert DuvallJames Caan

Where as I want it returned as:

Actor
Marlon Brando
Al Pacino
Diane Keaton
Robert Duvall
James Caan

Thanks for any help
