Question

Can anyone help me out in getting the below with an array..I have to generate the generalised xsl.. Input XML:

Answer 1

More generalized solution. Requires XSLT 2.0

Applied to the provided sample XML, produces following output:

    
        
            
                
                    john
                    
                
                
                    john
                    
                
            
        
    

The above solution was tested on this site: http://xslttest.appspot.com/

EDIT:

every $x in */name() satisfies $x=$firstNodeName is XPATH 2.0 construction that checks if all the elements in */name() sequence are equal to $firstNodeName. So this whole condition actually means checking if a node has more than one child with the same name - this is a condition for checking if we're dealing with json:array case.
