[java] view plaincopyprint?

    对应的xml文件：  


[html] view plaincopyprint?

    <?xml version="1.0" encoding="UTF-8"?>  
      
    <jim>  
      <first1 name="你好.doc" id="3"/>  
      <first1 name="ok" id="1">  
        <first1 name="oh.ppt" id="2"/>  
        <first1 name="8" id="1">  
          <first1 name="myGod.doc" id="1"/>  
          <first1 name="oh.ppt" id="2"/>  
        </first1>  
        <first1 name="second" id="3">  
          <first1 name="mytest.doc" id="1"/>  
          <first1 name="null" id="2"/>  
        </first1>  
      </first1>  
      <first1 name="z" id="2">  
        <first1 name="mytest.doc" id="1"/>  
        <first1 name="test.doc" id="2"/>  
      </first1>  
    </jim>  

比如jim/second/mytest.doc会转换成jim/3/1。
