Of course.

<xsl:call-template name="split_years">
<xsl:with-param name="year_list" select="text()"/>
</xsl:call-template>
</tr>
</xsl:template>
<xsl:template name="split_years">
<xsl:param name="year_list"/>
<xsl:choose>
<!-- if there's a comma, take everything before it... -->
<xsl:when test="contains($year_list,',')">
<xsl:variable name="year" select="normalize-space(substring-before($year_list,','))"/>
<!-- only make a table cell if there is non-whitespace before the comma -->
<xsl:if test="$year">
<td>
<xsl:value-of select="$year"/>

</xsl:if>
<!-- ...then go process everything after it -->
<xsl:call-template name="split_years">

</xsl:call-template>
</xsl:when>
