I have tried with:

-- //V14/V16/VEH[not(@tap=preceding::VEH/@tap)]  --
  it gives the VEH wich diferent values of 'tap' but that exists in the 
whole document.

--
//V14/V16/VEH[not(@tap=preceding::V14[cod='1CA8ADH7P5..A0']/V16/VEH/@tap)]  
--
  it gives back all the VEH


--
//V14[cod='1CA8ADH7P5..A0']/V16/VEH[not(@tap=preceding::V14[cod='1CA8ADH7P5..A0']/V16/VEH/@tap)]
-- //V14[cod='1CA8ADH7P5..A0']/V16/VEH[not(@tap=preceding::VEH/@tap)]

  both xpath give nothing.


I have tried with a lot more but they had no sense, I'm lost...

I want that when select a 'V14' in the select of versions the select of 
'tap' fill automatic without repeating values, and the same with 'colores' 
and 'as'.

I will look for information there to seeing if I find something.
