Re: how to increment a variable in a for-each loop

<xsl:for-each select="."> contains always only the current element, so the
position is always 1 -> red background. Remove the for-each and it will
work. A shortened version of your template:

<xsl:template match="*" mode="diff_cols">
    <fo:table-cell  background-color="red">
        <xsl:if test="position() mod 2 = 0">
            <xsl:attribute name="background-color">blue</xsl:attribute>
        </xsl:if>
        <fo:block><xsl:value-of select="."/></fo:block>
    </fo:table-cell>
</xsl:template>

Regards,

Joerg
