I still get empty parent nodes that are not filtered, since I left out the info. that attribute filter is also present on the parent node. It can also be empty or contain information. If you say you left out the info, does that mean you don't group anymore, only filter? And in the example below, what do you want to do with Article forename="John"? If you filter out the elements with filter='food', the first Document will not be included. That would leave out John too, although he has a filter='food'. <Documents> The best solution depends on what exactly you want to do. If it's plain filtering, a slight variation on the identity template would do: <xsl:template match="*"> <xsl:copy> <xsl:copy-of select="@*"/> <xsl:apply-templates select="*[@filter='food']"/> </xsl:copy> </xsl:template> that would give: <Documents> <Document id="0002" filter="food"> <Article surname="Jones" filter="food"/> </Document> </Documents> It might be a good idea to put the filter string in a global parameter: <xsl:stylesheet ...> <xsl:param name="filter" select="'food'"/> ... <xsl:apply-templates select="*[@filter=$filter]"/> If you still want to combine grouping and filtering, that's also possible: <xsl:template match="Documents"> <Documents> <xsl:for-each select="Document[@filter=$filter]/Article[count(.|key('by-info',@info)[1])=1]"> <Document name="{@info}"> <xsl:copy-of select="key('by-info',@info)[@filter=$filter]"/> </Document> </xsl:for-each> </Documents> </xsl:template> Best regards, Anton
