Re: Following-sibling node test

I am trying to output a list of all 'ref' attributes for which the
corresponding 'HTML' element is empty. For example, given the following xml
data, I would want to output ['2','3','4','5']. The final element in the
list should *not* be followed by a comma. I am tying to use the
following-sibling node test but it's not working. How can I test for these two conditions (HTML element is not empty, and is last item in list)?

<xsl:template name="SectionNumbers">
  <xsl:for-each select="/Content/Section[not(HTML = '')]">
	   <xsl:text>'</xsl:text>
	   <xsl:value-of select="@ref"/>
	   <xsl:choose>
			<xsl:when test="following-sibling::*[not(HTML = '')]">
				 <xsl:text>',</xsl:text>
			</xsl:when>
			<xsl:otherwise>
				 <xsl:text>'</xsl:text>
			</xsl:otherwise>
	   </xsl:choose>
  </xsl:for-each>
</xsl:template>

regards,
