Question

I have a XML as below -

</Page14>

For the above XML, I need to write an xslt that runs for each RegionRow element and within each region, I need to group first based on LOB element and then under that I need to do a sum of element 'Sum' based on certain ledger accounts.

I am trying to write the xslt as below -

<?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:wd="urn:com.workday.report/CR_Page_14_EMC"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:statutorytype="us-stat-2020-annual-stmt-pc"
    xmlns:xbrli="http://www.xbrl.org/2001/instance" xmlns:iso4217="http://www.xe.com/iso4217.htm"
    xmlns:stat="urn:www-iasa-org/tempuri" exclude-result-prefixes=" wd xs" version="2.0">
    
    <xsl:output indent="yes" method="xml"/>
    
    <xsl:variable name="single_quote">
        <xsl:text>'</xsl:text>
    </xsl:variable>
    <xsl:variable name="ampersand">
        <xsl:text>&amp;</xsl:text>
    </xsl:variable>
    
    <xsl:template match="Page14">
        <OutputOfNextXSL>
            <xsl:for-each select="RegionRow">
                <RowData>
                    <Region>
                        <xsl:value-of select="Region"/>
                    </Region>
                    <xsl:for-each-group select="EachUniqueCombo" group-by="EachUniqueCombo[LOB = '24 Surety']">
                        <CellOneAllied>
                            <!-- ledger account xyz, -->
                            <xsl:value-of
                                select="-1 * sum(EachUniqueCombo[LedgerAccount = '40000' or LedgerAccount = '20000']/xs:decimal(Sum))"/>
                            
                        </CellOneAllied>
<CellTwoAllied>
</CellTwoAllied>
---
--
                    </xsl:for-each-group>
<xsl:for-each-group select= EachUniqueCombo group-by=EachUniqueCombo[LOB = '16 Workers' Compensation']">
  <!-- Sum here based on one or multiple ledger accounts-->
</xsl:for-each-group>

The group by can be based on 1 LOB or multiple and similarly the ledger account/spend category inside that grouping based on which I need to do a sum can also be single or multiple. I am not able to get any value based on above group-by logic and then also cannot reach the ledger account or spend category inside the group to be able to do a sum. Can someone please help achieve this?

So you just want to "group" the same "LedgerAccount"-Tag with the sum von "Sum"-Tag in each "RegionRow"-Tag

Following XSLT-Code will make this:

XSLT 

<?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:xsi="http://www.w3.org/2001/XMLSchema-instance" exclude-result-prefixes="#all" version="2.0">
  <xsl:output method="xml" encoding="UTF-8"/>
  <xsl:template match="/">
<RegionRow>

  <xsl:for-each select="//RegionRow"> <!-- seach all RegionRow-Tags -->
     <xsl:for-each-group select="./EachUniqueCombo" group-by="LedgerAccount"> <!-- in each RegionRow-Tag group same LedgerAccounts -->
     <xsl:variable name="key" select="current-grouping-key()"/> <!-- save current key in variable "key" to get the right siblings -->
          <EachUniqueCombo>
               <key><xsl:value-of select="$key"/></key>
               <Sum><xsl:value-of select="sum(//Sum[../LedgerAccount/text()=$key])"/></Sum> <!-- sum of all same LedgerAccounts / get each Sum-Tag, which has a sibling with the current LedgerAccount (key) -->
          </EachUniqueCombo>
     </xsl:for-each-group>
  </xsl:for-each>

</RegionRow>

  </xsl:template>
</xsl:stylesheet>

XML-Output for our Sample for the first

<?xml version="1.0" encoding="UTF-8"?>
<RegionRow>
    <EachUniqueCombo>
        <key>20000</key>
        <Sum>-516</Sum>
    </EachUniqueCombo>
    <EachUniqueCombo>
        <key>20100</key>
        <Sum>110</Sum>
    </EachUniqueCombo>
    <EachUniqueCombo>
        <key>24000</key>
        <Sum>328.32</Sum>
    </EachUniqueCombo>
    <EachUniqueCombo>
        <key>40000</key>
        <Sum>-43</Sum>
    </EachUniqueCombo>
    <EachUniqueCombo>
        <key>40010</key>
        <Sum>-845.58</Sum>
    </EachUniqueCombo>
    <EachUniqueCombo>
        <key>50000</key>
        <Sum>-570</Sum>
    </EachUniqueCombo>
    <EachUniqueCombo>
        <key>50100</key>
        <Sum>-110</Sum>
    </EachUniqueCombo>
    <EachUniqueCombo>
        <key>51000</key>
        <Sum>-3.3499999999999996</Sum>
    </EachUniqueCombo>
</RegionRow>
