// TODO Auto-generated method stub
Document document = DocumentHelper.parseText(str);

Element users=document.getRootElement();

for(Iterator iter= users.elementIterator(); iter.hasNext(); ){

Element element = (Element)iter.next();

Attribute CategoryCode = element.attribute("CategoryCode");

Attribute CategoryName = element.attribute("CategoryName");

Attribute RegionID = element.attribute("RegionID");

Attribute RegionName = element.attribute("RegionName");

Attribute RegionValue = element.attribute("RegionValue");

System.out.println(CategoryCode.getText());

System.out.println(CategoryName.getText());

System.out.println(RegionID.getText());

System.out.println(RegionName.getText());

System.out.println(RegionValue.getText());

}
}

}

请问一下,如何获取:GameRegionItem这个子节点里面的的属性值呢?,如果GameRegionItem里面还有子节点呢?
