XSLT Ignore duplicate elements across multiple files

Question

I recently asked a question regarding how to ignore multiple elements, and got some good responses regarding using \'preceding\' and the Muenchian Method. However I was wond

Basically keys are built per document so a direct key based Muenchian grouping will not allow you to identify and remove duplicates in more than one document.

You could however first merge the two documents into one and then apply the Muenchian grouping to the merged document.

If you want to merge and group in one stylesheet you need to use exsl:node-set or similar:

  

  
  

  
    
      

        
      
    
    
   

  
    
  

  
    
    

      

        
Type
        
Count
      
      
  

  
    
  

  
    
      
        
      
      
        
      
    
  

You would now pass your index.xml as the main input document to the stylesheet.

If you want to do this transformation in the IE browser then you need to replace the exsl:node-set with Microsoft's ms:node-set (with the proper namespace) or you need to use the approach in http://dpcarlisle.blogspot.de/2007/05/exslt-node-set-function.html to make sure the exsl:node-set function is implemented.
