<xsl:element name="Heading"> <xsl:attribute name="entry"> <xsl:value-of select="Heading/@entry"/> </xsl:attribute> <xsl:value-of select="current-grouping-key()"/> </xsl:element> I believ you could replace that with <xsl:copy-of select=Heading"/> <xsl:for-each-group select="current-group()" group-by="SubHeading"> so all elements in the current group that don't have a heading should be get key () which isn't grouped, but you want a group so instead of grouping on the element (which may not be there) group on its string value (which will be "" so unheaded items will be grouped with key "") You could test for that but if you replace <xsl:element name="SubHeading"> <xsl:value-of select="current-grouping-key()"/> </xsl:element> by <xsl:copy-of select="SubHeading"/> There is no need to test, it will just do nothing if there is no heading.
