["Charles Ohana" <cohana@xxxxxxxxxxxxxxx>]

Hello Friends,

I have the following xml. and I need to get all the child/@name sorted and
without duplication.
</root>
   <child name="joe" />
   <child name="chris" />
   <child name="chuck" />
   <child name="alex" />
   <child name="chris" />
   <child name="joe" />
</root>

I need the following output "alex, chris, chuck, joe" .

any idea ?
