This stylesheet:

Output:

    some text
    
        some text
        
            some text
            some text
        
    

Also, this stylesheet:

Note: First stylesheet use most fine grained transversal (it will wrap any node after first item). Second stylesheet full recursive identity transform.

Edit: Addressing new requeriment, with new input, both stylesheets output:

    some text
    
        
            some text
            some text
        
        some text
        
            some text
            some text
