xslt node-set use in key function - find children by parent attribute

Question

I have an XML File.

Answer 1

Although this is not simple, I think you are making it much more complicated than it needs to be. Try the following stylesheet (not tested very thoroughly):

XSLT 1.0

    newid_answer
    newid_number








    
        
             
        
        
    



    

    
        
            
        
    

    

    
        
    
    
        
    

Note: when you are in the context of a node-set created by the exslt:node-set() function, you cannot use a key() to lookup data in the source XML document, unless you switch the context to the source document first.
