XSLT: moving a grouping html elements into section levels

Question

I\'m trying to write an XSLT that organizes an HTML file into different section levels depending on the header level. Here is my input:

Answer 1

A more general grouping in XSLT 1.0

Output:

    

        HEADER 1 CONTENT
        
Level 1 para
        
Level 1 para
        
Level 1 para
        
Level 1 para
        

            Header 2 CONTENT
            
Level 2 para
            
Level 2 para
            
Level 2 para
            
Level 2 para
        
    

And with a more complex input sample like:

    
1
    
1
    
1.1
    
2
    
1.1.1
    
3
    
1.2
    
4
    
2
    
5
    
2.1

Output:

    

        1
        
1
        

            1.1
            
2
            

                1.1.1
                
3
