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>
