Hi, Thanks for your solution. But with XSL logic below, If input XML is as shown below: <?xml version="1.0"?> <root> <ReservationControlInformationSegment> <CompanyId>AAH</CompanyId> <ReservationControlNumber>ABC12345</ReservationControlNumber> <ReservationControlType>A</ReservationControlType> <FirstDate>11OCT2007</FirstDate> <Time>1230</Time> <CompanyId>AAA</CompanyId> <ReservationControlType>B</ReservationControlType> <FirstDate>11OCT2007</FirstDate> <Time>1130</Time> </ReservationControlInformationSegment> </root> Then Expected output will be: <?xml version='1.0' ?> <root> <RCI> <RCI01> <RCI0101>AAH</RCI0101> <RCI0102>ABC12345</RCI0102> <RCI0103>A</RCI0103> <RCI0104>11OCT2007</RCI0104> <RCI0105>1230</RCI0105> </RCI01> <RCI02> <RCI0201>AAA</RCI0201> <RCI0202/> <RCI0203>B</RCI0203> <RCI0204>11OCT2007</RCI0204> <RCI0205>1130</RCI0205> </RCI02> </RCI> </root> But the actual output is coming with the given XSL as below: <?xml version='1.0' ?> <root> <RCI> <RCI01> <RCI0101>AAH</RCI0101> <RCI0102>ABC12345</RCI0102> <RCI0103>A</RCI0103> <RCI0104>11OCT2007</RCI0104> <RCI0105>1230</RCI0105> </RCI01> <RCI02> <RCI0201>AAA</RCI0201> <RCI0202>B</RCI0202> <RCI0203>11OCT2007</RCI0203> <RCI0204>1130</RCI0204> </RCI02> </RCI> </root> Our requirement for the output is: If any information is missing in the middle then empty tag should be there. But if it is missing at the end, then empty tags need not be there in the output. In input XML, elements will be in the same order. None of the elements are mandatory. Any of the elements can be missed in the input XML. For this requirement we need solution. --- Mukul Gandhi <gandhi.mukul@xxxxxxxxx> wrote: > This problem is easily solved with the XSLT 2.0 > grouping construct. > Please refer to the solution below: > > <?xml version="1.0" encoding="UTF-8"?> > <xsl:stylesheet > xmlns:xsl="http://www.w3.org/1999/XSL/Transform" > version="2.0"> > > <xsl:output method="xml" indent="yes" /> > > <xsl:template match="/root"> > <root> > <RCI> > <xsl:for-each-group > select="ReservationControlInformationSegment/*" > group-starting-with="CompanyId"> > <xsl:variable > name="aReservationControlInformation">RCI<xsl:number > value="position()" > format="01"/> > </xsl:variable> > <xsl:element > name="{$aReservationControlInformation}"> > <xsl:for-each select="current-group()"> > <xsl:variable > name="aReservationControlInformationNew"> > <xsl:value-of > select="$aReservationControlInformation" > /><xsl:number > value="position()" > format="01"/> > </xsl:variable> > <xsl:element > name="{$aReservationControlInformationNew}"> > <xsl:value-of select="." /> > </xsl:element> > </xsl:for-each> > </xsl:element> > </xsl:for-each-group> > </RCI> > </root> > </xsl:template> > > </xsl:stylesheet> > > On Nov 22, 2007 3:05 PM, lakshmi mrudula > <mrudula_lakshmi@xxxxxxxxx> wrote: > > Hi, > > > > We have the below issue in XSL logic.
