Issue with Accumulator in XSLT3.0 - xslt

Question

I have the below data from one data source,
<Reference>
<Worker>
<Employee_ID>1234</Employee_ID>
<Salary_Type>H</Salary_Type>
</Worker>
<Worker>
<Employee_ID>5678</Employee_ID>
<Salary_Type>H</Salary_Type>
</Worker>
</Reference>
the below data come from another data source,
<root>
<row>
<ID>1234</ID>
<ADDR>ABC</ADDR>
<PHONE>9999999998</PHONE>
<SAL>S</SAL>
</row>
<row>
<ID>5678</ID>
<ADDR>ABD</ADDR>
<PHONE>9999999999</PHONE>
<SAL>S</SAL>
</row>
</root>
I have merged the data from these data sources and have the following data,
<root>
<Reference>
<Worker>
<EmployeeID>1234</Employee_ID>
<SalaryType>H</Salary_Type>
</Worker>
<Worker>
<EmployeeID>5678</Employee_ID>
<SalaryType>H</Salary_Type>
</Worker>
</Reference>
<root>
<row>
<ID>1234</ID>
<ADDR>ABC</ADDR>
<PHONE>9999999998</PHONE>
<SAL>S</SAL>
</row>
<row>
<ID>5678</ID>
<ADDR>ABD</ADDR>
<PHONE>9999999999</PHONE>
<SAL>S</SAL>
</row>
</root>
</root>
In XSLT3.0 I m trying to replace the value of <SAL> with value of <SalaryType> with the following code, buts its not working.
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:map="http://www.w3.org/2005/xpath-functions/map"
xmlns:xs="http://www.w3.org/2001/XMLSchema" exclude-result-prefixes="#all" version="3.0">
<xsl:mode streamable="no" on-no-match="shallow-copy" use-accumulators="#all"/>
<xsl:output method="xml" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:accumulator name="EIDKey" as="xs:string" initial-value="''" streamable="yes">
<xsl:accumulator-rule match="/root/Reference/Worker/EmployeeID/text()" select="."/>
</xsl:accumulator>
<xsl:accumulator name="PayTypeLookup" as="map(xs:string,xs:string)" initial-value="map {}"
streamable="yes">
<xsl:accumulator-rule match="/root/Reference/Worker/SalaryType/text()"
select="map:put($value, accumulator-before('EIDKey'), string(.))"/>
</xsl:accumulator>
<xsl:template match="/">
<root>
<xsl:for-each select="root/root/row">
<row>
<xsl:apply-templates/>
</row>
</xsl:for-each>
</root>
</xsl:template>
<xsl:template match="SAL">
<xsl:variable name="PayType" select="normalize-space(.)"/>
<SAL><xsl:value-of select="accumulator-before('PayTypeLookup')($PayType)"/></SAL>
</xsl:template>
</xsl:stylesheet>
I need the final output like below, can you please help? Thanks in advance
<root>
<row>
<ID>1234</ID>
<ADDR>ABC</ADDR>
<PHONE>9999999998</PHONE>
<SAL>H</SAL>
</row>
<row>
<ID>5678</ID>
<ADDR>ABD</ADDR>
<PHONE>9999999999</PHONE>
<SAL>H</SAL>
</row>
</root>

Answer 1

I think you need another accumulator
<xsl:accumulator name="rowID" as="xs:string" initial-value="''" streamable="yes">
<xsl:accumulator-rule match="/root/root/row/ID/text()" select="."/>
</xsl:accumulator>
and then you can use
<xsl:template match="SAL">
<SAL><xsl:value-of select="accumulator-before('PayTypeLookup')(accumulator-before('rowID'))"/></SAL>
</xsl:template>
