Hi everybody,
 
Does anyone know a way to do a list in a XSL file in a ...
<xsl:for-each select="SgPlantTypes/SgPlantType" order-by="@FCOLOR">...
... and eliminate the elements (or simply not display these ...) or nodes that the FCOLOR is the same (ex: 3 elements as @FCOLOR="red" and 3 "red" appear in the list ... but I want just to see one "red"...)
 
Thnaks in advance for any answer,
Regards,
