        RootElement root = new RootElement(RSS);
        final List<Message> messages = new ArrayList<Message>();
        Element itemlist = root.getChild(CHANNEL);
        Element item = itemlist.getChild(ITEM);
        item.setEndElementListener(new EndElementListener(){
            @Override
            public void end() {
                messages.add(currentMessage.copy());
            }

        item.getChild(LINK).setEndTextElementListener(new EndTextElementListener(){
            @Override
            public void end(String body) {
                currentMessage.setLink(body);
            }
        });
        item.getChild(DESCRIPTION).setEndTextElementListener(new EndTextElementListener(){
            @Override
