I don't think anyone's shown you a recursive template to do this, so
here's one:

<xsl:template name="substring-after-last">
   <xsl:param name="string" />
   <xsl:param name="delimiter" select="'.'" />
   <xsl:choose>
      <xsl:when test="not(contains($string, $delimiter))">
         <xsl:value-of select="$string" />
      </xsl:when>
      <xsl:otherwise>
         <xsl:call-template name="substring-after-last">
            <xsl:with-param name="string"
               select="substring-after($string, $delimiter)" />
            <xsl:with-param name="delimiter"
                            select="$delimiter" />
         </xsl:call-template>
      </xsl:otherwise>
   </xsl:choose>
</xsl:template>

Cheers,
