Hi,

I want to achieve the following xml using simple xml framework (http://simple.sourceforge.net/):

<events>
    <course-added date="01/01/2010">
        ...
    </course-added>
    <course-removed date="01/02/2010">
        ....
    </course-removed>
    <student-enrolled date="01/02/2010">
        ...
    </student-enrolled>
</events>

I have the following (but it doesn't achieve the desired xml):

@Root(name="events")
class XMLEvents {

    @ElementList(inline=true)
    ArrayList<XMLEvent> events = Lists.newArrayList();

        ...
}


abstract class XMLEvent {

    @Attribute(name="date")
    String dateOfEventFormatted;

    ...

}

And different type of XMLNodes that have different information (but are all different types of events)

@Root(name="course-added")
class XMLCourseAdded extends XMLEvent{

    @Element(name="course") 
    XMLCourseLongFormat course;

    ....
}

@Root(name="course-removed")
class XMLCourseRemoved extends XMLEvent {

    @Element(name="course-id")
    String courseId;

        ...

}

How should I do the mapping or what should I change in order to be able to achieve de desired xml?

Thanks!
