Hi,
 
Here I want to select the FCOLOR attribute for each element ... and display only one time each color found in the XML file ...
 
Does anyone know a way to do this ???
 
Here is the context: 

<xsl:for-each select="SgPlantTypes/SgPlantType" order-by="@FCOLOR">
<DIV CLASS="listItem">
<A TARGET="weedsFCList">
<xsl:attribute name="HREF" >
weedsFCList.asp?color=<xsl:value-of select="@FCOLOR" />
</xsl:attribute>
<xsl:value-of select="@FCOLOR"/>
</A>
</DIV>
</xsl:for-each>

Thanks in advance for any answer,
Regards,
