关于生成的XML文件内容显示排序的问题

Question

现在生成XML文件是这样显示的，乱的不行<?xml version="1.0" encoding="GB2312"?><地图编辑器配置文件 MapHeight="16" MapWidth="20" TitleHeight="16" TitleWidth="16" Title网格线="显示" 双图层="否" 图片索引="-1" 地图块网格线="显示" 地图网格线="显示" 差异色显示翻转="不是" 类型="0" 网格线="显示" 风格="0"/>
如何能弄成这种现实效果呢？
<?xml version="1.0" encoding="UTF-8"?> 
<java version="1.5.0_06" class="java.beans.XMLDecoder"> 
 <object class="javax.swing.tree.DefaultMutableTreeNode"> 
  <void property="userObject"> 
   <string>图片</string> 
  </void> 
  <void method="add"> 
   <object class="javax.swing.tree.DefaultMutableTreeNode"> 
    <void property="allowsChildren"> 
     <boolean>false</boolean> 
    </void> 
    <void property="userObject"> 
     <string>D:\Tools\Editor\0.png</string> 
    </void> 
   </object> 
  </void>
