Now I want to add another 'select', ('opciones'), if I use the same form to refill it, the number of different combinations it turns almost impossible. There is another form to do it?

I tried with something like this:

<xsl:key name="o4" match="VEH" use="concat(@codcol,'+',@tap,'+',@opt)"/>
<xsl:key name="o3" match="VEH" use="concat(@codcol,'+',@opt)"/>
<xsl:key name="o2" match="VEH" use="concat(@tap,'+',@opt)"/>
<xsl:key name="o1" match="VEH" use="@opt"/>
<!-- ... -->
<td>
<xsl:attribute name="class"><xsl:value-of select="$clase"/></xsl:attribute>
<select>
<xsl:attribute name="name"><xsl:value-of select="//FILTRO/OPT/@nombre"/></xsl:attribute>
<option value="0">
<xsl:value-of select="//LIT/@SELECCIONE"/>
</option>
<!--xsl:apply-templates
select="//V14[@cod=$v14 or $v14='0']/V16[@as=$as or $as='0']/VEH[generate-id()=generate-id(key('o1',@opt)[1])]/@opt">
<xsl:sort select="." data-type="text" order="ascending"/>
</xsl:apply-templates-->
<xsl:choose>
<xsl:when test="$color!='0' and $tap!='0'">
<xsl:apply-templates
select="//V14[@cod=$v14 or $v14='0']/V16[@as=$as or $as='0']/VEH[generate-id()=generate-id(key('o4',concat($color,'+',$tap,'+',@opt))[1])]/@opt">
<xsl:sort select="." data-type="text" order="ascending"/>
</xsl:apply-templates>
</xsl:when>
<xsl:when test="$color!='0' and $tap='0'">
<xsl:apply-templates
select="//V14[@cod=$v14 or $v14='0']/V16[@as=$as or $as='0']/VEH[generate-id()=generate-id(key('o3',concat($color,'+',@opt))[1])]/@opt">
<xsl:sort select="." data-type="text" order="ascending"/>
</xsl:apply-templates>
</xsl:when>
<xsl:when test="$color='0' and $tap!='0'">
<xsl:apply-templates
select="//V14[@cod=$v14 or $v14='0']/V16[@as=$as or $as='0']/VEH[generate-id()=generate-id(key('o2',concat($tap,'+',@opt))[1])]/@opt">
<xsl:sort select="." data-type="text" order="ascending"/>
</xsl:apply-templates>
</xsl:when>
<xsl:when test="$color='0' and $tap='0'">
<xsl:apply-templates
select="//V14[@cod=$v14 or $v14='0']/V16[@as=$as or $as='0']/VEH[generate-id()=generate-id(key('o1',@opt)[1])]/@opt">
<xsl:sort select="." data-type="text" order="ascending"/>
</xsl:apply-templates>
</xsl:when>
</xsl:choose>
</select>
</td>
<!-- ... -->
<xsl:template match="@opt">
<OPTION>
<xsl:attribute name="value"><xsl:value-of select="."/></xsl:attribute>
<xsl:value-of select="."/>
</OPTION>
</xsl:template>

But it doesn't work in all the cases, some options are absent in the 'select' that they should be there.

For example, if i put:

<xsl:param name="v14" select="'1CA8A5J7P5..A0'"/><!-- 1CA8A5J6P5..A0 1CA8A5J7P5..A0 -->
<xsl:param name="as" select="'31'"/>
<xsl:param name="color" select="0"/> <!-- J4 -->
<xsl:param name="tap" select="0"/> <!-- Z2FT Z2FZ -->

the options in the select must be: 'WL45, 58J0, 95HC, 58H9' but there are only '58J0, 95HC, 58H9'.

I hope that someone can help me, and say how to optimize this xsl.


Thanks for all.
