<xsl:template match="top">
<top>
  <xsl:call-template name="SecoundTemplate" >
    <xsl:with-param name="nodes" select="dig" />
  </xsl:call-template>
</top>


</xsl:template>
<xsl:template name="SecoundTemplate" >
<xsl:param name="nodes"  />
<xsl:choose>
   <xsl:when test="name(preceding-sibling::*[1]) !='CoTooooooooooooooo' "/>
     <xsl:otherwise>
    <CoTo>
      <xsl:call-template name="FinalTemplate">
        <xsl:with-param name="nodes" select="$nodes[position() >0 ]" />
      </xsl:call-template>
    </CoTo>
    <xsl:call-template name="SecoundTemplate">
      <xsl:with-param name="nodes" select="$nodes[position() >6]" />
    </xsl:call-template>
    </xsl:otherwise>
</xsl:choose>
</xsl:template>



<xsl:template name="FinalTemplate" >
<xsl:param name="nodes"  />
<xsl:param name="count" select="1" />
  <xsl:choose>
    <xsl:when test="($count = 7) or (name(following-sibling::*[1])
!='$nodes') )   "/>
    <xsl:otherwise>
      <dig><xsl:value-of select="$nodes[1]" /> </dig>
        <xsl:call-template name="FinalTemplate">
        <xsl:with-param name="nodes" select="$nodes[position() > 1]" />
        <xsl:with-param name="count" select="$count + 1" />
        </xsl:call-template>
    </xsl:otherwise>
  </xsl:choose>
</xsl:template>
</xsl:stylesheet>
