Answer 1

Here is a pure XSLT 1.0 solution that doesn't use any extensions:

when this transformation is applied on the provided XML document:

  
    
    
  

  
    
      testFizz
      
        testBar
        testLib
      
    
    
      testFizz2
      
        testBar2
        testLib2
      
    
  

the wanted, correct result is produced:

    
        
    
    
        

            

                
Foo Bar
                
Fizz
            
            

                
testBar
                
testFizz
            
            

                
testBar2
                
testFizz2
