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

Hi Kobily,


This should be only for the elements that have content (tgis have
been solved), my problem is to give the number of each elem. I can´t
increase a variable. I´m using:

<xsl:variable name="values">0</xsl:variable>
<xsl:for-each select="elem">
<option><xsl:attribute name="value"><xsl:value-of select="$values + 1"/></xsl:attribute><xsl:value-of select="elem"/></option>
</xsl:for-each>


But the variable "values" is always 1.


Variables are strange in XSLT, in that they don't vary. But XSLT gives you other ways of doing what you want to do. In your case, you can use the position() function to get a counter telling you which elem you're currently on. So you can do:

  <xsl:for-each select="elem">
    <option>
      <xsl:attribute name="value">
        <xsl:value-of select="position()" />
      </xsl:attribute>
      <xsl:value-of select="." />
    </option>
  </xsl:for-each>

Or, more simply using an attribute value template:

  <xsl:for-each select="elem">
    <option value="{position()}">
      <xsl:value-of select="." />
    </option>
  </xsl:for-each>

[I've assumed that the content of the option element should be the
value of the current elem, not the value of the elem element child of
the current elem element.]
I hope that helps,


Jeni
