Hi Mukul ,
  Thanks a lot. But I have got two more elements at the end.
  This requirement I got it a couple of hours ago.
  I am just wondering whether is it possible.
  Your help is really appreciated. Thanks in adavnce.
  <ns:MT_Test xmlns:ns="http://Centrica/Test";>
  <RECSETNAME xmlns:ns="http://Centrica/Test";>
    <Record>
        <keyfieldValue>HEADR</keyfieldValue>
        <fieldValue>CDJOB</fieldValue>
        <fieldValue>TRA</fieldValue>
    </Record>
    <Record>

        <fieldValue>BRITISH TELECOM</fieldValue>
    </Record>
    <Record>

        <fieldValue>INSTL</fieldValue>
        <fieldValue>METER</fieldValue>

Subject: Re: [xsl] XSLT to conver flat XML to Heirarchy XML

Please try this 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" indent="yes" />

<xsl:template match="/">
  <xsl:call-template name="xyz">
    <xsl:with-param name="x" select="//Record[1]" />
  </xsl:call-template>
</xsl:template>

<xsl:template name="xyz">
  <xsl:param name="x" />
 
  <xsl:if test="$x">
    <xsl:element name="{$x/keyfieldValue}">
      <xsl:for-each select="$x/fieldValue">
        <fieldValue><xsl:value-of select="."
/></fieldValue>
      </xsl:for-each>
      <xsl:call-template name="xyz">
        <xsl:with-param name="x"
select="$x/following-sibling::Record[1]" />
      </xsl:call-template>
    </xsl:element>
  </xsl:if>
</xsl:template>

</xsl:stylesheet>

I feel double quote characters (") in element values are erroneous (or
you require them?).. So I omitted "
from the XML document.

When the above XSLT stylesheet is applied to XML -

<ns:MT_Test xmlns:ns="http://Centrica/Test";>
  <RECSETNAME xmlns:ns="http://Centrica/Test";>
    <Record>
        <keyfieldValue>HEADR</keyfieldValue>
        <fieldValue>CDJOB</fieldValue>
        <fieldValue>TRA</fieldValue>
    </Record>
    <Record>
        <keyfieldValue>TRANS</keyfieldValue>
        <fieldValue>DATA</fieldValue>
        <fieldValue>EXCHG</fieldValue>
        <fieldValue>EXCH</fieldValue>
    </Record>
    <Record>
        <keyfieldValue>MTPNT</keyfieldValue>
        <fieldValue>74842606</fieldValue>
    </Record>
    <Record>
        <keyfieldValue>ADDRS</keyfieldValue>
        <fieldValue>MTRPT</fieldValue>
        <fieldValue>BRITISH TELECOM</fieldValue>
    </Record>
    <Record>
        <keyfieldValue>ASSET</keyfieldValue>
        <fieldValue>INSTL</fieldValue>
        <fieldValue>METER</fieldValue>
    </Record>
    <Record>
        <keyfieldValue>METER</keyfieldValue>
        <fieldValue>T</fieldValue>
    </Record>
  </RECSETNAME>
</ns:MT_Test>

The output recieved is -

<?xml version="1.0" encoding="UTF-8"?>
<HEADR>
   <fieldValue>CDJOB</fieldValue>
   <fieldValue>TRA</fieldValue>
   <TRANS>
      <fieldValue>DATA</fieldValue>
      <fieldValue>EXCHG</fieldValue>
      <fieldValue>EXCH</fieldValue>
      <MTPNT>
         <fieldValue>74842606</fieldValue>
         <ADDRS>
            <fieldValue>MTRPT</fieldValue>

   </Record>

 </RECSETNAME>
</<ns:MT_Test>

All the data is store under the record structure,

based on the

keyFieldValue i have to generate the target node.

my Target XML should look like:

<HEADR>
  <fieldValue>"CDJOB"</fieldValue>
  <fieldValue>"TRA"</fieldValue>
  <TRANS>
    <fieldValue>"DATA"</fieldValue>
    <fieldValue>"EXCHG"</fieldValue>
    <fieldValue>"EXCH"</fieldValue>

    <MTPNT>
      <fieldValue>74842606</fieldValue>

      <ADDRS>
         <fieldValue>"MTRPT"</fieldValue>
         <fieldValue>"BRITISH

TELECOM"</fieldValue>

      </ADDRS>

      <ASSET>
         <fieldValue>"INSTL"</fieldValue>
         <fieldValue>"568"</fieldValue>

         <METER>
            <fieldValue>"T"</fieldValue>
         </METER>
      </ASSET>
    <MTPNT>
  </TRANS>
</HEADR>



The logic for generating:

  loop through the records in sorce xml,

   Base on the key value generate the note in the

tareget XML, The

problem here is i am not sure how to insert the

nodes as a children in

the targt.



Could anyone please help.

Sreekanth
