Multiple Counters in XSLT - xslt

Question

I need to maintain 2 counters in my xslt - EntryID and RowID. I have a xml which contains Name and Certifications the person holds. Now I need to maintain one counter for each person (EntryID) and one for each certification (RowID). And on top of the certifications, I need to add one more certification "New" which will have a RowID one number higher than the maximum number certifications the person holds.
Below is the XML:
<?xml version='1.0' encoding='UTF-8'?>
<wd:Report_Data xmlns:wd="urn:com.workday.report/bsvc">
<wd:Report_Entry>
<Name>Ram</Name>
<Certifications>
<Certificate>AWS</Certificate>
<Certificate>Workday</Certificate>
<Certificate>SAP</Certificate>
</Certifications>
</wd:Report_Entry>
<wd:Report_Entry>
<Name>Nitin</Name>
<Certifications>
<Certificate>Workday</Certificate>
</Certifications>
</wd:Report_Entry>
<wd:Report_Entry>
<Name>Joe</Name>
<Certifications>
<Certificate>SAP</Certificate>
<Certificate>AWS</Certificate>
</Certifications>
</wd:Report_Entry>
</wd:Report_Data>
The expected output is below. The name should appear only in the first row.
EntryID,Name,RowID,Certification
1,Ram,1,AWS
1,,2,Workday
1,,3,SAP
1,,4,NEW --> New certificate with row id 4 as Ram already has 3 certifications
2,Nitin,1,Workday --> Entry ID is 2 for Nitin and Row ID restarts from 1
2,,2,NEW
3,Joe,1,SAP
3,,2,AWS
3,,3,NEW
The XSLT I am able to build so far, but not giving desired output.
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema"

xmlns:etv="urn:com.workday/etv"
exclude-result-prefixes="xs wd" version="3.0">
<xsl:output method="text" indent="yes"/>
<xsl:template match="/">
<xsl:variable name="delimeter" select="','"/>
<xsl:variable name="lineFeed" select="'
'"/>
<root>
<xsl:for-each select="wd:Report_Data/wd:Report_Entry">
<EntryID><xsl:value-of select="position()"/></EntryID>
<xsl:value-of select="$delimeter"/>
<Name><xsl:value-of select="Name"/></Name>
<xsl:value-of select="$delimeter"/>
<xsl:for-each select="Certifications/Certificate">
<RowID><xsl:value-of select="position()"/></RowID>
<xsl:value-of select="$delimeter"/>
<xsl:value-of select="."/>
</xsl:for-each>
<xsl:value-of select="$lineFeed"/>
<EntryID><xsl:value-of select="position()"/></EntryID>
<xsl:value-of select="$delimeter"/>
<xsl:value-of select="$delimeter"/>
<text>NEW</text>
<xsl:value-of select="$lineFeed"/>
</xsl:for-each>
</root>
</xsl:template>
</xsl:stylesheet>
Please help me with correct XSLT.

Answer 1

To produce the wanted output with XSLT 3, I would use something like
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="3.0"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
exclude-result-prefixes="#all"
xmlns:wd="urn:com.workday.report/bsvc"
expand-text="yes">
<xsl:param name="delimeter" select="','"/>
<xsl:param name="lineFeed" select="'
'"/>
<xsl:output method="text"/>
<xsl:template match="wd:Report_Data">
<xsl:value-of select="'EntryID','Name','RowID','Certification'" separator="{$delimeter}"/>
<xsl:value-of select="$lineFeed"/>
<xsl:apply-templates select="wd:Report_Entry"/>
</xsl:template>
<xsl:template match="wd:Report_Entry">
<xsl:apply-templates select="Certifications/Certificate"/>
</xsl:template>
<xsl:template match="Certificate">
<xsl:variable name="entry-id" as="xs:integer">
<xsl:number count="wd:Report_Entry"/>
</xsl:variable>
<xsl:variable name="row-id" as="xs:integer">
<xsl:number/>
</xsl:variable>
<xsl:value-of select="$entry-id, (../../Name[$row-id = 1], '')[1], $row-id, ." separator="{$delimeter}"/>
<xsl:value-of select="$lineFeed"/>
<xsl:if test="position() = last()">
<xsl:value-of select="$entry-id, '', $row-id + 1, 'NEW'" separator="{$delimeter}"/>
<xsl:value-of select="$lineFeed"/>
</xsl:if>
</xsl:template>
</xsl:stylesheet>

The XML result you show can be produced quite easily using:
XSLT 1.0
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:wd="urn:com.workday.report/bsvc"
exclude-result-prefixes="wd">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:template match="/wd:Report_Data">
<root>
<xsl:for-each select="wd:Report_Entry">
<row>
<EntryID>
<xsl:value-of select="position()" />
</EntryID>
<Name>
<xsl:value-of select="Name" />
</Name>
<xsl:for-each select="Certifications/Certificate">
<Certificate>
<RowID>
<xsl:value-of select="position()" />
</RowID>
<cName>
<xsl:value-of select="." />
</cName>
</Certificate>
</xsl:for-each>
<Certificate>
<RowID>
<xsl:value-of select="count(Certifications/Certificate) + 1" />
</RowID>
<cName>NEW</cName>
</Certificate>
</row>
</xsl:for-each>
</root>
</xsl:template>
</xsl:stylesheet>
To get a "flat" CSV output, you can do:
XSLT 1.0
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:wd="urn:com.workday.report/bsvc">
<xsl:output method="text" encoding="UTF-8"/>
<xsl:template match="/wd:Report_Data">
<!-- header -->
<xsl:text>EntryID,Name,RowID,Certification
</xsl:text>
<!-- data -->
<xsl:for-each select="wd:Report_Entry">
<xsl:variable name="entry-data">
<xsl:value-of select="position()" />
<xsl:text>,</xsl:text>
<xsl:value-of select="Name" />
<xsl:text>,</xsl:text>
</xsl:variable>
<!-- output -->
<xsl:for-each select="Certifications/Certificate">
<xsl:copy-of select="$entry-data"/>
<xsl:value-of select="position()" />
<xsl:text>,</xsl:text>
<xsl:value-of select="." />
<xsl:text>
</xsl:text>
</xsl:for-each>
<!-- new certificate -->
<xsl:copy-of select="$entry-data"/>
<xsl:value-of select="count(Certifications/Certificate) + 1" />
<xsl:text>,NEW
</xsl:text>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
which in XSLT 3.0 can be reduced to:
<xsl:stylesheet version="3.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:wd="urn:com.workday.report/bsvc"
expand-text="yes">
<xsl:output method="text" encoding="UTF-8"/>
<xsl:template match="/wd:Report_Data">
<!-- header -->
<xsl:text>EntryID,Name,RowID,Certification
</xsl:text>
<!-- data -->
<xsl:for-each select="wd:Report_Entry">
<xsl:variable name="entry-data">{position()},{Name}</xsl:variable>
<!-- output -->
<xsl:for-each select="Certifications/Certificate, 'NEW'">{$entry-data},{position()},{.}
</xsl:for-each>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
