how to change nesting structure in XML using XSLT?-CodePudding

I'm a complete XSLT new beginner but I need to use it for a project I'm working on.

I have an XML file thant looks like this:

<?xml version="1.0" encoding="UTF-8"?>

<table>
   <CLASS>
      <Name></Name>
      <Sex></Sex>
      <Age></Age>
      <Height></Height>
      <Weight></Weight>
   </CLASS>
</table>

and my desired output should look like this

<table>
   <CLASS>
      <Name> 
     <Sex>
          <Age>
              <Height>              
            <Weight>
            </Weight>
          </Height>
         </Age>
        </Sex>
      </Name>
   </CLASS>
</table>

I have now spent 2 days but I'm not able to fine a solution for that. I tried using for-each and read about grouping but unsure how to perform such change in nesting structure. I'm using XSLT 1.

This doesn't look as a task suitable for "a complete XSLT noob".

Assuming that each element under CLASS is supposed to be nested inside its immediately preceding sibling, you could adapt a method known as "sibling recursion":

XSLT 1.0

<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:strip-space elements="*"/>

<xsl:template match="/table">
    <xsl:copy>
        <xsl:apply-templates/>
    </xsl:copy>
</xsl:template>

<xsl:template match="CLASS">
    <xsl:copy>
        <xsl:apply-templates select="*[1]"/>
    </xsl:copy>
</xsl:template>

<xsl:template match="CLASS/*">
    <xsl:copy>
        <xsl:apply-templates select="following-sibling::*[1]"/>
    </xsl:copy>
</xsl:template>

</xsl:stylesheet>
