Hi,

In XSLT1.0, you'd have to use some recursively called template that does  
some string-realted tests.

e.g.:

<xsl:template match="eleccionusuario_valor">
	<xsl:call-template name="number"/>
</xsl:template>

<xsl:template name="number">
	<xsl:param name="index" select="1"/>
	<xsl:param name="string" select="."/>
	<xsl:if test="substring-before($string,',') = 'true'">
		<xsl:value-of select="$index"/>
		<xsl:if test="contains(substring-after($string,','), 'true')">
			<xsl:text>,</xsl:text>
		</xsl:if>		
	</xsl:if>
	<xsl:if test="contains($string,',')">
		<xsl:call-template name="number">
			<xsl:with-param name="string" select="substring-after($string,',')"/>
			<xsl:with-param name="index" select="$index + 1"/>
		</xsl:call-template>
	</xsl:if>
</xsl:template>

(tested with AltovaXSLT)
