<xsl:output method="xml"  indent="yes"/>
	
<xsl:template match="/SHAPE">
  <SHAPE>
    <xsl:copy-of select="ELEM_INFO"/>
    <xsl:variable name="x"
select="ELEM_INFO/ELEM_INFO_ITEM[1]"/>
    <xsl:variable name="y"
select="ELEM_INFO/ELEM_INFO_ITEM[4]"/>
    <xsl:variable name="z"
select="ELEM_INFO/ELEM_INFO_ITEM[7]"/>
    <COORDINATES>
       <xsl:for-each
select="COORDINATES/COORDINATES_ITEM">
	  <xsl:choose>
	    <xsl:when test="(position() = $x) or (position()
= $y) or (position() = $z)">
	      <COORDINATES_ITEM>
		<xsl:value-of select="concat('d',.)"/>
	      </COORDINATES_ITEM>
 	    </xsl:when>
  	    <xsl:otherwise>
 	      <COORDINATES_ITEM>
		<xsl:value-of select="."/>
