RE: Finding and restructuring duplicate elements


I want to transform this XML:

<A id=1>
    <AA id=1/>
    <AA id=2/>
</A>
<A id=2>
    <AA id=1>data1</AA>
    <AA id=2>text1</AA>    <<-- These two nodes to be split...
    <AA id=2>text2</AA>    <<-- These two nodes to be split...
</A>

TO:

<A id=1>
    <AA id=1/>
    <AA id=2/>
</A>
<A id=2>
    <AA id=1>data1</AA>
    <AA id=2>text1</AA>
</A>
<A id=2_1>
    <AA id=1>data1</AA>
    <AA id=2>text2</AA>
</A>


This is a rather unusual variant of the usual grouping problems. But I'm not
sure the requirements are well specified. How would you want to handle the
following, for example:

<A id=2>
     <AA id=1>data1</AA>
     <AA id=2>text1</AA>   
     <AA id=2>text2</AA>  
     <AA id=3>textZ</AA>   
     <AA id=3>textX</AA>    
     <AA id=3>textC</AA>   
     <AA id=4>textV</AA>      
</A>
