Function document() : access to all elements (continue

Thanks a lot David and Michael for your comments,                     
                                                                      
I modified my template with your sugestion but I still can not        
get what I want, in fact I still can not understand how the document  
function works.                                                       
                                                                      
                                                                      
Sorry for sending the following code but I didn't find a better       
way to explain my problem.                                            
                                                                      
                                                                      
I want to output

I would appreciate your comments.                                     
                                                                      
                                                                      
A proposal for doing this is:

this does only the first element.
