转化平面列表到嵌套的列表

Question

我有一些XML其描述书如下：

<root> 
    <chapter> 
     <chapter_number>some chapter</chapter_number> 
     <chapter_title>some title</chapter_title> 

     <heading_1>some heading</heading_1> 

     <para>some plain text <italic>some italic text</italic> some more text</para> 

     <list_1_letter>item 1</list_1_letter> 
     <list_1_letter>item 2</list_1_letter> 
     <list_2_bullet>sub-item 1</list_2_bullet> 
     <list_2_bullet>sub-item 2</list_2_bullet> 
     <list_1_letter>item 3</list_1_letter> 

     <para>some other text</para> 

     <list_1_number>item 1</list_1_number> 
     <list_2_roman>sub-item 1</list_2_roman> 
     <list_2_roman>sub-item 2</list_2_roman> 
     <list_1_number>item 2</list_1_number> 
     <list_2_roman>sub-item 3</list_2_roman> 
     <list_2_roman>sub-item 4</list_2_roman> 
    </chapter> 
</root> 

名单需要被包裹在描述他们的元素，但子列表应该是列表的孩子在他们上面。在这种情况下，所需的输出将是：

<root> 
    <chapter> 
     <chapter_number>some chapter</chapter_number> 
     <chapter_title>some title</chapter_title> 

     <heading_1>some heading</heading_1> 

     <para>some plain text <italic>some italic text</italic> some more text</para> 

     <letter_list> 
      <list_1_letter>item 1</list_1_letter> 
      <list_1_letter>item 2</list_1_letter> 
      <bullet_list> 
       <list_2_bullet>sub-item 1</list_2_bullet> 
       <list_2_bullet>sub-item 2</list_2_bullet> 
      </bullet_list> 
      <list_1_letter>item 3</list_1_letter> 
     </letter_list> 

     <para>some other text</para> 

     <number_list> 
      <list_1_number>item 1</list_1_number> 
      <roman_list> 
       <list_2_roman>sub-item 1</list_2_roman> 
       <list_2_roman>sub-item 2</list_2_roman> 
      </roman_list> 
      <list_1_number>item 2</list_1_number> 
      <roman_list> 
       <list_2_roman>sub-item 3</list_2_roman> 
       <list_2_roman>sub-item 4</list_2_roman> 
      </roman_list> 
     </number_list> 
    </chapter> 
</root> 

适应从这里一些其他的答案，我可以换名单，但我只能换同一个列表的顺序，就会产生：

<number_list> 
    <list_1_number>item 1</list_1_number> 
</number_list> 
<roman_list> 
    <list_2_roman>sub-item 1</list_2_roman> 
    <list_2_roman>sub-item 2</list_2_roman> 
</roman_list> 
<number_list> 
    <list_1_number>item 2</list_1_number> 
</number_list> 
<roman_list> 
    <list_2_roman>sub-item 3</list_2_roman> 
    <list_2_roman>sub-item 4</list_2_roman> 
</roman_list> 

并不完全一样！这比我预期的更有效。
