i want no double xml records to be viewed

Hello,  
Please take a look at my problem. 

I have xml-records with a tag that have the same  content, like 
this tag: 
<PPN>12345</PPN>, I want just one record to be  shown in 
my ie-explorer, is it possible to add a  line in my stylesheet to 
prevent this?
