This compete and short transformation:

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

 <xsl:template match="/*">
     <Parent>
      <xsl:apply-templates/>
     </Parent>
 </xsl:template>

 <xsl:template match="Child">
   <xsl:element name="{@key}"><xsl:apply-templates/></xsl:element>
 </xsl:template>
</xsl:stylesheet>

when applied on the provided XML document:

<Parent>
 <Children>
 <Child key="Name">ABC</Child>
 <Child key="Age">8</Child>
 <Child key="Height">140</Child>
 <Child key="Class">6</Child>
 </Children>
</Parent>

produces the wanted, correct result:

<Parent>
   <Name>ABC</Name>
   <Age>8</Age>
   <Height>140</Height>
   <Class>6</Class>
</Parent>
