Re: Remove duplicates from a list

Hi Clark,
  Thanks for your help. But unfortunately it still does not work for me. I am 
using xslp as my xsl processor. I have attached the xml and xsl code. Could you 
take a look at it when you have a few moments to spare, please? Thanks a lot. I 
hope I'm not bothering you.
  
Minita.
