The whitespace in the groups may be problematic. As long as a group is considered empty if the value of all elements is only whitespace, too, you could try this: use the generic copy template: <xsl:template match="@*|node()"> <xsl:copy> <xsl:apply-templates select="@*"/> <xsl:apply-templates /> </xsl:copy> </xsl:template> and add a template which matchs the elements whose stringvalue is only whitespace and does nothing. <xsl:template match="*[not(normalize-space())]" /> -- Ingo Schildmann Development WiredMinds Informationssysteme GmbH email: Ingo.Schildmann@xxxxxxxxxxxxx XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
