Hi Dave,
  Please try this XSL. It uses the Muenchian
technique.

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

<xsl:key name="by-group-name" match="group"
use="@name" />

<xsl:template match="/root">
  <root>
    <xsl:for-each select="group[generate-id(.) =
generate-id(key('by-group-name', @name)[1])]">
      <group name="{@name}">
        <xsl:for-each select="key('by-group-name',
@name)">
          <xsl:copy-of select="*"/>
        </xsl:for-each>
      </group>
    </xsl:for-each>
  </root>
</xsl:template>

</xsl:stylesheet>
