Conversion Between XML and object using xstream

Offical site said, but it does not make it clearly. Especial Parse XML with attributes. Here is my test according to docs from offical websites.

public class XstreamTest {        public static void main(String[] args) throws Exception {        //convertXml2();        convertObject2();    }        public static void convertXml1(){        RendezvousMessage1 message = new RendezvousMessage1(1, false, "part1","part2","part3");        XStream xStream = new XStream(new DomDriver());        xStream.processAnnotations(RendezvousMessage1.class);        System.out.println("message1 "+xStream.toXML(message));    }    public static String convertXml2(){        RendezvousMessage2 message = new RendezvousMessage2(1, false, "part1","part2","part3");        XStream xStream = new XStream(new DomDriver());        xStream.processAnnotations(RendezvousMessage2.class);        System.out.println("message2 "+xStream.toXML(message));        String xmlString = xStream.toXML(message);        return xmlString;    }        public static void convertObject2(){                XStream xStream = new XStream(new DomDriver());        xStream.processAnnotations(RendezvousMessage2.class);        System.out.println("convertObject2 "+xStream.fromXML(convertXml2()));    }    }@XStreamAlias("message")class RendezvousMessage1 {    @XStreamAlias("type")       @XStreamAsAttribute    private int messageType;    @XStreamImplicit(itemFieldName="part")    private List<String> content;           @XStreamAsAttribute    @XStreamConverter(value=BooleanConverter.class, booleans={false}, strings={"yes", "no"})    private boolean important;    public RendezvousMessage1(int messageType, boolean important, String... content) {        this.messageType = messageType;        this.important = important;        this.content = Arrays.asList(content);    }}@XStreamAlias("message")class RendezvousMessage2 {       @XStreamAsAttribute    private int type;    @XStreamImplicit(itemFieldName="part")    private List<String> content;           @XStreamAsAttribute    @XStreamConverter(value=BooleanConverter.class, booleans={false}, strings={"yes", "no"})    private boolean important;    public RendezvousMessage2(int messageType, boolean important, String... content) {        this.type = messageType;        this.important = important;        this.content = Arrays.asList(content);    }    @Override    public String toString() {        return "type "+type+" content "+content;    }}

Through my test, it work well.
