Answer 1

I like to use XMLBeam for such tasks:

public class Answer {

    @XBDocURL("resource://data.xml")
    public interface DataProjection {

        public interface Topic {
            @XBRead("./@id")
            int getID();

            @XBRead("./@percentage")
            String getPercentage();
        }

        @XBRead("/modelingOutput/listOfDocs//document/topic")
        List getTopics();
    }

    public static void main(final String[] args) throws IOException {
        final DataProjection dataProjection = new XBProjector().io().fromURLAnnotation(DataProjection.class);
        for (Topic topic : dataProjection.getTopics()) {
            System.out.println(topic.getID() + ": " + topic.getPercentage());
        }
    }
}

There is even a convenient way to convert the percentage to float or double. Tell me if you like to have an example.
