Context error on for-each on tokenize variable

Question

I am using XSLT 2.0 and have a variable who contains dates separated by comma. I try to tokenize this variable in a for-each but in execution, I have the error: "Cannot select a node here: the context item is an atomic value"

Here is my code:

<xsl:variable name="datesMois">
    <xsl:call-template name="dayOfMonth">
        <xsl:with-param name="pDay" select="01" />
        <xsl:with-param name="pMonth" select="/workfile/query/@month" />
        <xsl:with-param name="pYear" select="/workfile/query/@year" />          
    </xsl:call-template>
</xsl:variable>
<xsl:variable name="currentstartdate" select="substring-before(., 'T')" />
<xsl:for-each select="tokenize($datesMois,',')">
    <xsl:variable name="dateJour" select="." />
...

The template dayOfMonth returns the days for the month given in parameters. I don't understand what is wrong in my code, could you please help me?

Thanks.

Please add more context to your question as well. That is, especially the code for the named template "dayOfMonth" - if not the entire stylesheet. Also, a sample XML input would help. — Mathias Müller

Assuming you have something like

<xsl:variable name="datesMois">
    <xsl:call-template name="dayOfMonth">
        <xsl:with-param name="pDay" select="01" />
        <xsl:with-param name="pMonth" select="/workfile/query/@month" />
        <xsl:with-param name="pYear" select="/workfile/query/@year" />          
    </xsl:call-template>
</xsl:variable>
<xsl:variable name="currentstartdate" select="substring-before(., 'T')" />
<xsl:for-each select="tokenize($datesMois,',')">
    <xsl:variable name="dateJour" select="." />
    <xsl:value-of select="foo[date = $dateJour]"/>

you would get the error you describe, to avoid that you would need to store the context node outside of the for-each in a variable as in

<xsl:variable name="datesMois">
    <xsl:call-template name="dayOfMonth">
        <xsl:with-param name="pDay" select="01" />
        <xsl:with-param name="pMonth" select="/workfile/query/@month" />
        <xsl:with-param name="pYear" select="/workfile/query/@year" />          
    </xsl:call-template>
</xsl:variable>
<xsl:variable name="currentstartdate" select="substring-before(., 'T')" />

<xsl:variable name="context" select="."/>

<xsl:for-each select="tokenize($datesMois,',')">
    <xsl:variable name="dateJour" select="." />
    <xsl:value-of select="$context/foo[date = $dateJour]"/>

I had to guess how your code might look that causes the error, if you still have problems then post the exact line of your code that causes the error.
