You have to use recursive template:

<xsl:template name="last">
    <xsl:param name="string"/>
    <xsl:choose>
        <xsl:when test="contains($string,'.')">
            <xsl:call-template name="last">
                <xsl:with-param name="$string"
select="substring-after($string,'.')"/>
            </xsl:call-template>
        </xsl:when>
        <xsl:otherwise>
            <xsl:value-of select="$string"/>
        </xsl:otherwise>
    </xsl:choose>
</xsl:template>
