Hello everybody :)

I want to test each value from a split string separated by a coma. How do i grab the value at a position in the split ie what is the value of split variable at position 2?

I'm currently trying to test for related articles by tags. If there are 2 or more articles found then show list of articles otherwise show nothing.

The code snippet is below with necessary information. The ???????? is the code bit that I'm unsure of how to write?

    <xsl:param name="tags" select="umbraco.library:Split($currentPage/data[@alias='tags'],',')"/>

    <xsl:template match="/">
        <xsl:call-template name="startModule">
            <xsl:with-param name="tagNum" select="count($tags/value)"/>
            <xsl:with-param name="count" select="1"/>
        </xsl:call-template>
    </xsl:template>

    <xsl:template name="startModule">
        <xsl:param name="count"/>
        <xsl:param name="tagNum"/>
        <xsl:variable name="tagValue" select="?????????"/>
        <xsl:variable name="tagArticleList" select="$currentPage/ancestor-or-self::node[@level='1']//node [@nodeTypeAlias = 'Blog Article' and contains(data[@alias='tags'],$tagValue)]"/>
        <xsl:variable name="tagArticleListNum" select="count($tagArticleList)"/>
        <xsl:choose>
            <xsl:when test="$tagArticleListNum &gt; 1">
                <xsl:call-template name="module"/>
            </xsl:when>
            <xsl:when test="$count &lt; $tagNum">
                <xsl:call-template name="startModule">
                    <xsl:with-param name="count" select="$count + 1"/>
                    <xsl:with-param name="tagNum" select="$tagNum"/>
                </xsl:call-template>
            </xsl:when>
            <xsl:otherwise></xsl:otherwise>
        </xsl:choose>
    </xsl:template>

    <xsl:template name="module">
        ....
    </xsl:template>
