Meanwhile try this: <xsl:key name="comments" match="comment" use="@page"/> <xsl:template match="comments"> <xsl:apply-templates select="comment[generate-id()=generate-id(key('comments',@page))]" mode="headers"/> </xsl:template> <xsl:template match="comment"> <xsl:apply-templates/> <xsl:text> </xsl:text> </xsl:template> <xsl:template match="comment" mode="headers"> <xsl:value-of select="substring(@page,1,4)"/> <xsl:text>-</xsl:text> <xsl:value-of select="substring(@page,5,2)"/> <xsl:text>-</xsl:text> <xsl:value-of select="substring(@page,7,2)"/> <xsl:text> </xsl:text> <xsl:apply-templates select="key('comments',@page)"/> </xsl:template> Hope this helps you XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
