One of the simplest and shortest template including logic towards your question would be:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
    
    <xsl:template match="@* | node()" name="identity-copy">
        <xsl:copy>
            <xsl:apply-templates select="@* | node()"/>
        </xsl:copy> 
    </xsl:template>
    
    <xsl:template match="class">
        <xsl:copy>
            <xsl:apply-templates select="@* | node()"/>
            <professor>SaiBaba</professor>
        </xsl:copy>
    </xsl:template>

</xsl:stylesheet>

@* matches all attributes

node() is a function to match all elements on child-axes with type

  • element
  • text-node
  • processing-instruction (PI) node
  • comment node

First template named indentity-copy is a 1:1 copy from source to output. See more infos at Wiki here.

The second template matches your element class, copies itself, and adds the element professor. Alternativ way: You can create the elements in a more strict version via XSL commands to reduce/avoid whitespace or namespace problems:

<xsl:element name="professor">
    <xsl:text>SaiBaba</xsl:text>
</xsl:element>
