> Hello,
> 
> 	I have a XML file with a lot of repeated information. 
> The question is how do I insert refs not repeating information:
> 
> For example if I have:
> 
> <email>
>       <to>John</to>
>       <to>Bill</to>
> </email>
> <email>
>       <to>John</to>
> </email>
> 
> I wnat the output to be:
> 
>       <to id ="id1">John</to>
>       <to id = "id2">Bill</to>
> 
>       <email>
>       	<to ref = "id1"/>
>       	<to ref = "id2"/>
>       </email>
>       <email>
>       	<to ref = "id1"/>
>       </email>
