Re: Finding and restructuring duplicate elements

Sorry about the unclear requirement...  

A couple of things to note:
There will only be ONE <AA> with attribute id=1,
There CAN be more than one <AA> with attribute id=xxx
There will ONLY be <AA> elements with two diff. attribute ids, id=1, and id=xxx.
and, id attribute for element <A> is actually ignored.
There can be duplicate <AA> elements (duplicate id attribute) across
different <A> element, but not within same <A> element.

So, worst case scenario for source XML would be:

 <A id=1>
      <AA id=1>data1</AA>
      <AA id=2>text1</AA>
 </A>
 <A id=2>
      <AA id=1>data1</AA>
      <AA id=2>text1</AA>
      <AA id=2>text2</AA>
      <AA id=2>text3</AA>
 </A>

and the desired target:

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

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

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

 <A id=2>
      <AA id=1>data1</AA>
      <AA id=2>text3</AA>
 </A>


I'm thinking of maybe creating a temp variable that will contain the
duplicate nodes within <A> and then recreate the resulting xml tree?
