输出的xml 格式为以下形式

<root>
<user>
<id>0</id>
<username>gaoxin</username>
<gamescore>0</gamescore>
<gamespendtime>00:00:01</gamespendtime>
<currentdate>2010-12-17 13:48:12</currentdate>
<grade>Primary</grade>
<rowcount>12</rowcount>
<colcount>10</colcount>
<gamestatus>UNSUCCESSFUL</gamestatus>
<spycount>15</spycount>
</user>
</root>

不知道各位大侠都怎样实现？求解对xml这不是很熟练，如果对一个一个的节点赋值组合太多垃圾代码

自己实现了一些但是在赋值的时候总是有问题 以下是实现代码段

Element root = document.createElement("root");

			// 添加到文档中
			document.appendChild(root);
			
			
			//创建子跟元素user
			for (int i = 0; i < list.size(); i++) {
				root.appendChild(document.createElement("user"));
			}

			//添加属性
			NodeList nodeList = document.getElementsByTagName("user");
						
			//添加子节点
			int size = nodeList.getLength();			
			for (int k = 0; k < size; k++) {
				Node node = nodeList.item(k);
				if (node.getNodeType() == Node.ELEMENT_NODE) {
					Element elementNode = (Element) node;
					
					//循环添加子节点
					for(int s=0; s<UserGameInfo.class.getFields().length; s++)
					{
						Field field = UserGameInfo.class.getFields()[s];
						        elementNode.appendChild(document.createElement(field.getName()));
					}
				}
			}

在对节点赋值的时候应该怎样具体操作 求解？ 谢谢

那帮忙给点提示撒~不要应代码的一个一个赋值。除了这个方法还有其他更方便的方法吗？
