Re: [xsl] Numbering

Hi Jenny
Here is the real case:

Part of the template match="root"
<select size="6" name="available">
<xsl:apply-templates select="*|@*|text()"/>
</select>

The template I´m calling:
<xsl:template match="@*|text()">
<xsl:if test="normalize-space(.)!=''">
<option value="{position()}">
<xsl:for-each select="ancestor::*">/<xsl:value-of 
select="local-name(.)"/></xsl:for-each>
</option>
</xsl:variable>
</xsl:if>
</xsl:template>

In this case, I get an html with:

<select name="second"><option value="1">/root/url</option><option 
value="1">/root/tags/a</option><option 
value="1">/root/tags/b</option><option 
value="1">/root/tags/c</option><option 
value="1">/root/tags/e</option><option 
value="1">/root/tags/f</option><option 
value="1">/root/tags/g</option><option 
value="1">/root/tags/i</option><option 
value="1">/root/tags/j</option></select>

So, I could not use position.

I hope you could help me.

Regards
