This list is intended for Saxon-specific questions - for general XSLT coding questions you might be better off on StackOverflow or on the mulberrytech xsl-list.

This is the classic use case for xsl:for-each-group/@group-starting-with. If we simplify the problem so you are turning

1.1

  

1.2

  

2

  

2.1

  

2.2



into



   
      
      
   
   
      
      
   




Then you can do


  
    
       
        
            
        
       
    
  



You can generalize this to an arbitrary number of levels by making it recursive: see my paper here:
