Thanks, David!!!

I was thinking to fill de 'selects' only with xpath and javascript, 
something like this:

 function cargarASalon(xPath) {
   limpia(form1.cmbASalon);
   insertOpt(form1.cmbASalon, "Seleccione", "0");

   var oASalon = oDatos.selectNodes(xPath);
   for(var j=0; oASalon.length > j; j++) {
     insertOpt(form1.cmbASalon, oASalon.item(j).getAttribute("as"),
                                             
oASalon.item(j).getAttribute("as"));
   }
 }

But now I am tried with xsl, i suppose that only with xpath maybe it will be 
impossible.

Well, now i have another problem.

I add a new node <PARAMS> in the xml that I can create before the 
transformation (I do not know how to pass params to the xsl)

	<PARAMS>
		<V14>1CA8ADH7P5..A0</V14>
		<AS>30</AS>
		<COL>0</COL>
		<TAP>0</TAP>
	</PARAMS>

I have created the next xsl:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
 <xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>

 <xsl:key name="a" match="V16" use="concat(../@cod,'+',@as)"/>
 <xsl:key name="c" match="VEH" 
use="concat(../../@cod,'+',../@as,'+',@codcol)"/>
 <xsl:key name="t" match="VEH" use="concat(../../@cod,'+',@tap)"/>
 <xsl:param name="v14" select="//PARAMS/V14"/>
 <xsl:param name="as" select="//PARAMS/AS"/>
 <xsl:param name="color" select="/PARAMS/COL"/>

 <xsl:template match="/DATOS">

You can see the <xsl:if>..</xsl:if>, with that I try to change 
generte-id(key(...))

-- this to use all 'as'
  <xsl:for-each 
select="//V14[@cod=$v14]/V16/VEH[generate-id()=generate-id(key('c',concat($v14,'+',@as,'+',@codcol))[1])]">

-- this to use only the 'as' which comes with 'params'
  <xsl:for-each 
select="//V14[@cod=$v14]/V16/VEH[generate-id()=generate-id(key('c',concat($v14,'+',$as,'+',@codcol))[1])]">


The idea is that the comboBoxes are linked, now i'm trying with 'colores' (i 
have the literals), but the idea is:
v14 -> as -> color -> tap, when i select one, the others must be to change 
with the good values.
(well, i know it, repeat myself, i told it yesterday)

It exists some wildcard to replace part of the key? It is necesary to repeat 
all the code? When I'll do the same thing with 'tap' i'll have several 
possible options (with 'as', without 'as', with 'color', without 'color'), 
how could I do to don't repeat the same code? or how use a variable with the 
good value or a wildcard? or cut the key? ...


Thank you for everything!!!


PD: Congratulations for the baby!!!
