amith swamySubject: Regarding XSLT logic for a simple input XML message
Author: amith swamy

We are facing an issue in XSL logic for a simple XML file. Please let us know about this.


If input XML has same elements that is repeating twice and should be mapped to the same element in the output XML..
For Ex:

If input XML is,
<?xml version="1.0"?>
<root>
<ReservationControlInformationSegment>
<CompanyId>AAH</CompanyId>
<ReservationControlNumber>ABC456789</ReservationControlNumber>
<CompanyId>AAH</CompanyId>
<ReservationControlNumber>ABC456789</ReservationControlNumber>
<ReservationControlType>B</ReservationControlType>
</ReservationControlInformationSegment>
</root>

In ReservationControlInformationSegment, three elements are there that can repeat any number of times(Consider 2 times). But in the above example for the first time, third element(ReservationControlType) is not present. Second time its present.

The expected output XML is
<root>
<RCI>
<RCI01>
<RCI0101>AAH</RCI0101>
<RCI0102>ABC456789</RCI0102>
</RCI01>
<RCI02>
<RCI0201>AAH</RCI0201>
<RCI0202>ABC456789</RCI0202>
<RCI0203>B</RCI0203>
</RCI02>
</RCI>
</root>

We have used the below XSL to get the output XML

<?xml version='1.0' ?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<root>
<RCI>
<xsl:for-each select="root/ReservationControlInformationSegment/CompanyId">
<xsl:variable name="PositionCount" select="position()"/>
<xsl:variable name="this" select="generate-id(.)"/>
<xsl:variable name="next" select="generate-id(following-sibling::ReservationControlNumber[1]/preceding-sibling::CompanyId[1])"/>
<xsl:variable name="reservationcontrolnumber">
<xsl:if test="$this = $next">
<xsl:value-of select="following-sibling::ReservationControlNumber[1]"/>
</xsl:if>
</xsl:variable>
<xsl:variable name="next1" select="generate-id(following-sibling::ReservationControlType[1]/preceding-sibling::CompanyId[1])"/>
<xsl:variable name="reservationcontroltype">
<xsl:if test="$this = $next1">
<xsl:value-of select="following-sibling::ReservationControlType[1]"/>
</xsl:if>
</xsl:variable>
<xsl:variable name="next3" select="generate-id(following-sibling::Time[1]/preceding-sibling::CompanyId[1])"/>
<xsl:variable name="time">
<xsl:if test="$this = $next3">
<xsl:value-of select="following-sibling::Time[1]"/>
</xsl:if>
</xsl:variable>
<xsl:variable name="aReservationControlInformation">RCI<xsl:number value="position()" format="01"/></xsl:variable>
<xsl:element name="{$aReservationControlInformation}">
<xsl:variable name="aCompanyId">RCI<xsl:number value="position()" format="01"/>01</xsl:variable>
<xsl:element name="{$aCompanyId}">
<xsl:value-of select="."/>
</xsl:element>
<xsl:variable name="aReservationControlNumber">RCI<xsl:number value="position()" format="01"/>02</xsl:variable>
<xsl:element name="{$aReservationControlNumber}">
<xsl:value-of select="$reservationcontrolnumber"/>
</xsl:element>
<xsl:variable name="aReservationControlType">RCI<xsl:number value="position()" format="01"/>03</xsl:variable>
<xsl:if test="following-sibling::ReservationControlType[1][normalize-space()]">
<xsl:element name="{$aReservationControlType}">
<xsl:value-of select="$reservationcontroltype"/>
</xsl:element>
</xsl:if>
</xsl:element>
</xsl:for-each>
</RCI></root>
</xsl:template>
</xsl:stylesheet>



But the O/P is in the following format where extra <RCI0103/> is coming
<?xml version="1.0"?>
<root>
<RCI>
<RCI01>
<RCI0101>AAH</RCI0101>
<RCI0102>ABC456789</RCI0102>
<RCI0103/>
</RCI01>
<RCI02>
<RCI0201>AAH</RCI0201>
<RCI0202>ABC456789</RCI0202>
<RCI0203>B</RCI0203>
</RCI02>
</RCI>
</root>


This is because while checking for the if condition we are checking for the following sibling of CompanyId.

Can you please suggest if there is any better approach to solve this problem?
