Hi Sasa,
  Please try the XSL --

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>

<xsl:output method="xml" version="1.0"
encoding="UTF-8" indent="yes"/>
<xsl:key name="x" match="Value" use="." />
<xsl:template match="/root">
   <xsl:for-each select="Item/Field">
     <xsl:if test="generate-id(Value) =
generate-id(key('x', Value)[1])">
         <xsl:value-of select="Value" />
     </xsl:if>
   </xsl:for-each>
</xsl:template>
</xsl:stylesheet>

The XSL above, uses Muenchian method for Grouping.

Regards,
Mukul
