I know this is not the most elegant solution, but it works:

Given this source XML-

<doc>
        <foo>split,this,string,please</foo>
</doc>

This stylesheet snippet...

<xsl:template match="foo">
        <xsl:call-template name="splitString">
                <xsl:with-param name="string1" select="."/>
        </xsl:call-template>
</xsl:template>
        
<xsl:template name="splitString">
        <xsl:param name="string1"/>
        <xsl:choose>
                <xsl:when test="contains($string1,',')">
                        <xsl:variable name="beforeComma"
select="substring-before($string1,',')"/>
                        <xsl:element name="entry"><xsl:value-of
select="$beforeComma"/></xsl:element>
                        <xsl:variable name="afterComma"
select="substring-after($string1,',')"/>
                        <xsl:call-template name="splitString">
                                <xsl:with-param name="string1"
select="$afterComma" />
                        </xsl:call-template>
                </xsl:when>
                <xsl:otherwise>
                        <xsl:element name="entry">
                                <xsl:value-of select="$string1"/>
                        </xsl:element>
                </xsl:otherwise>
        </xsl:choose>
</xsl:template>

...produces the following output:

<entry>split</entry>
<entry>this</entry>
<entry>string</entry>
<entry>please</entry>


Of course you can modify this to suit your personal requirements.
