Hi Ghandi,

Sorry for late response.  This might be a nice alternative solution to
the one from George.  I tested it but for some reason, I get only the
values in the output without the xml tags.

Regards
Houman

Hi Houman,
   This is an example of positional grouping.

Following is one solution to this problem:

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

  <xsl:output method="xml" indent="yes" />

  <xsl:template match="/root">
    <root>
      <xsl:for-each select="*">
        <xsl:choose>
          <xsl:when test="not(self::Attribute)">
            <xsl:copy-of select="." />
          </xsl:when>
          <xsl:when test="not(preceding-sibling::*[1]/self::Attribute)">
            <OtherAttributes>
               <xsl:copy-of select="." />
               <xsl:call-template name="MakeGroup">
                 <xsl:with-param name="nodeset"
select="following-sibling::*" />
               </xsl:call-template>
            </OtherAttributes>
          </xsl:when>
        </xsl:choose>
      </xsl:for-each>
    </root>
  </xsl:template>

  <xsl:template name="MakeGroup">
    <xsl:param name="nodeset" />

    <xsl:if test="$nodeset[1]/self::Attribute">
      <xsl:copy-of select="$nodeset[1]" />
      <xsl:call-template name="MakeGroup">
        <xsl:with-param name="nodeset" select="$nodeset[position() &gt;
1]" />
      </xsl:call-template>
    </xsl:if>
  </xsl:template>

</xsl:stylesheet>

For e.g., when the above stylesheet is applied to XML:

<root>
  <a>1</a>
  <b>2</b>
  <Attribute>
    <Name>xx</Name>
    <Value>xx</Value>
  </Attribute>
  <Attribute>
    <Name>yy </Name>
    <Value>yy</Value>
  </Attribute>
  <c>3</c>
</root>

The following output is produced:

<?xml version="1.0" encoding="UTF-8"?>
<root>
   <a>1</a>
   <b>2</b>
   <OtherAttributes>
      <Attribute>
         <Name>xx</Name>
         <Value>xx</Value>
      </Attribute>
      <Attribute>
         <Name>yy </Name>
         <Value>yy</Value>
      </Attribute>
   </OtherAttributes>
   <c>3</c>
</root>

Regards,
Mukul
