need to replace map with variable value-CodePudding

I have xslt and below code works fine, however I need to replace "map{"abc": "yes","dDEF": "Yes","RMT": "dsfdf","PPAS": "Yes","UNITE": "Yes"}" with variable

<xsl:variable name="var_res">
        <xsl:value-of select='map:for-each(map{"abc": "yes","dDEF": "Yes","RMT": "dsfdf","PPAS": "Yes","UNITE": "Yes"}, function($k, $v){ 
          {
            if($v!="Yes" and $v!="No")
            then $k else ""})' />             
        </xsl:variable>

as below :

        <xsl:variable name="var_mapValue" >
            <xsl:value-of select="/root/input/collective_barg"></xsl:value-of>
            
        </xsl:variable>



      <xsl:variable name="var_res">
        <xsl:value-of select='map:for-each(map(var_mapValue)}, function($k, $v){ 
          {
            if($v!="Yes" and $v!="No")
            then $k else ""})' />             
        </xsl:variable>

map(var_mapValue) doesn't work not sure what is missing here

and my input xml

 <?xml version="1.0" encoding="UTF-8"?>
<root>
<input>
<collective_barg>
{"abc": "yes","dDEF": "Yes","RMT": "dsfdf","PPAS": "Yes","UNITE": 
"Yes"}
</collective_barg>
</input>
</root>

To parse the JSON and turn it into what the XML Data Model defines as a "map", you should use the XPath 3.1 function parse-json() https://www.w3.org/TR/xpath-functions-31/#func-parse-json

<xsl:variable name="map" select="parse-json(/root/input/collective_barg)"/>

Also NB string comparison in XSLT is case sensitive; the string value Yes is not equal to yes. I suggest you use the upper-case() (or lower-case()) function to normalize the text and then compare it to "YES" (or "yes").

By the way, when you are declaring a variable, you can just assign its value using the select attribute; you don't need to enclose an xsl:value-of element. Using xsl:value-of just has the effect of converting the data to a string. If you really do want to convert it to a string, you can use the string() function. e.g. don't do this:

<xsl:variable name="var">
        <xsl:value-of select="blah"/>         
        </xsl:variable>

do this:

<xsl:variable name="var" select="blah"/>

or if you do want to convert the input to a string, do this:

<xsl:variable name="var" select="string(blah)"/>

var_mapValue is a variable.

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                version="3.0">
    <xsl:template match="/root">
        <xsl:variable name="var_mapValue">
            <xsl:value-of select="/input/collective_barg"/>
        </xsl:variable>
        <xsl:variable name="var_res">
            <xsl:value-of select='map:for-each($var_mapValue, function($k, $v){ 
          
            if($v!="Yes" and $v!="No")
            then $k else ""})'/>
        </xsl:variable>
        <test>
            <xsl:value-of select="$var_res"/>
        </test>
    </xsl:template>
</xsl:stylesheet>
