Instead of testing for city inside the for-each, why not only select the Person elements you want? I.e. first <xsl:for-each select="Person[City]"> <xsl:value-of select="concat(Name, ' - ', City)"/> </> And then <xsl:text>People not connected to city:</xsl:text> <xsl:for-each select="Person[not(City)]"> <xsl:value-of select="concat(Name, ' - ', City)"/> </> Cheers, Jarno
