Answer 1

You can use two approaches, one is a direct representation of your desired JSON as XDM 3.1 maps and arrays:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:xs="http://www.w3.org/2001/XMLSchema"
    xmlns:map="http://www.w3.org/2005/xpath-functions/map"
    exclude-result-prefixes="#all"
    version="3.0">


  <xsl:output method="json" indent="yes"/>

  <xsl:template match="/*">
    <xsl:sequence
      select="map {
        local-name() : array {
          map:merge(* ! map {
            lower-case(local-name()) : serialize(node())
          })
        }
      }"/>
  </xsl:template>
  
</xsl:stylesheet>

The second would be to transform your input XML into the XML representation of JSON the xml-to-json function uses.
