Dynamic grouping on element and attributes names

Question

I would like to categorize results from an XPath under headings by element name (and then by same attribute names). Note: XML data could be inconsistent and some elements with t

This stylesheet:

    
    
        
            
        
    
    
        
                    
                
        

            

                
ElementName

Note: This assumes that all elements having the same number of attributes have also the same attribute's name (like in your input sample).

EDIT: Better ouput markup.

EDIT 2: Another kind of solution: one header with all posible attribute (like CSV pattern) and order element by attribute count and name.

    
    
    
        
            
                        
                    
                    
                    
                

                

                    
ElementName

Note: This runs through the tree twice but without extension. Exact match for desired output without extensions would require to mimic key mechanism like this: run through the tree adding new keys (name of element plus attributes' names) to a param, then again for every key run through the tree filtering node by key (could be a little optimization keeping a node set for non matching elements...). Worst case (every node with distinc key) will pass trough a node: N (for key building) + (N + 1) * N / 2
