[xsl] Numbering

[kobily <kobily at netscape dot net>]

Hi !!!

I have to create a list of options:
<select>
<option value="1">Some
<option value="2">some-elem
<option value="3">other elem
</select>

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.


Thanks
