Re: [xsl] Issue with repetition of elements in the input XML

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.

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"?>

                       version="2.0">

  <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: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>

Hi,

We have the below issue in XSL logic. Can you

please

provide us better approach to solve the issue?
Issue is mentioned below.

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>ABC12345</ReservationControlNumber>

<ReservationControlType>A</ReservationControlType>
<FirstDate>11OCT2007< /FirstDate>
<Time>1230</Time>
<CompanyId>AAA</CompanyId>

<ReservationControlNumber>ABC456739</ReservationControlNumber>

<ReservationControlType>B</ReservationControlType>
<FirstDate>11OCT2007< /FirstDate>

<Time>1130</Time></ReservationControlInformationSegment>

</root>


The expected output XML is

<root>
<RCI>
<RCI01>
<RCI0101>AAH</RCI0101>
<RCI0102> ABC12345</RCI0102>
<RCI0103>A</RCI0103>
<RCI0104>11OCT2007</RCI0104>
<RCI0105>1230</RCI0105>
</RCI01>
<RCI02>
<RCI0201>AAA</RCI0201>
<RCI0202>ABC456739</RCI0102>
<RCI0203>B</RCI0103>
<RCI0204>11OCT2007</RCI0104>
<RCI0205>1130</RCI0105>
</RCI02>
</RCI>
</root>

The XSL used is as shown below

<RCI>
<xsl:for-each

select="root/ReservationControlInformationSegment/CompanyId">

<xsl:variable name="PositionCount"
select="position()"/>
<xsl:variable name="this"

select="generate-id(.)"/>

select="generate-id(following-sibling::ReservationControlNumber[1]/preceding-sibling::CompanyId[1])"/>

<xsl:variable name="reservationcontrolnumber">
<xsl:if test="$this = $next">

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">

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

value="position()" format="01"/></xsl:variable>
<xsl:element

<xsl:variable name="aCompanyId">RCI<xsl:number

</xsl:if>
<xsl:variable name="aTime">RCI<xsl:number

<xsl:if

test="following-sibling::Time[1][normalize-space()]">

<xsl:element name="{$aTime}">

</xsl:element>
</xsl:if>
</xsl:element>
</xsl:for-each>
