How to read XML document using JAXB

I need to parse large xml. And I tried to do it in the following way:

Testing FilmParser.java class:

public class FilmParser {
    public static void main(String args[]) throws IOException, Exception{

    List<Film> filmList= new ArrayList<Film>(); 

    String xml = "<?xml version='1.0' encoding='utf-8' ?>  <film-list>  <item company=\"New Line Cinema\" year=\"1995\" film=\"Se7en\" />  <item company=\"Warner Brothers\" year=\"2005\" film=\"Batman Begins\" /> <item company=\"Larner Brothers\" year=\"2010\" film=\"Inception\" /> </film-list>";
    Document doc = loadXMLFromString(xml);
     Node baseNode = doc.getFirstChild(); 

        NodeList children = baseNode.getChildNodes();
        for (int i = 0; i < children.getLength(); i++) {
            Node item = children.item(i);
            if (item.getNodeType() == Node.ELEMENT_NODE) {
                String company = item.getAttributes().getNamedItem("company").getTextContent();
                int year = Integer.parseInt(item.getAttributes().getNamedItem("year").getTextContent());
                String film = item.getAttributes().getNamedItem("film").getTextContent();
                Film filmObj = new Film(company, year, film);
                filmList.add(filmObj);
                System.out.println(filmObj);
            }
        }

  }

  private static Document loadXMLFromString(String xml) throws Exception
  {
      DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
      DocumentBuilder builder = factory.newDocumentBuilder();
      InputSource is = new InputSource(new StringReader(xml));
      return builder.parse(is);
  }

}

And Film.java class:

public class Film {
    private String company;
    private int year;
    private String film;

    public Film(){  
    }

    public Film(String company, int year, String film) {
        super();
        this.company = company;
        this.year = year;
        this.film = film;
    }
    public String getCompany() {
        return company;
    }
    public void setCompany(String company) {
        this.company = company;
    }
    public int getYear() {
        return year;
    }
    public void setYear(int year) {
        this.year = year;
    }
    public String getFilm() {
        return film;
    }
    public void setFilm(String film) {
        this.film = film;
    }

    @Override
    public String toString() {
        return "Film [company=" + company + ", year=" + year + ", film=" + film
                + "]";
    }

}

Please explain how could I actually rewrite this using JAXB, and do not parse xml manually.
