Re: Changing row colors using variables

Hi Steve,

the only problem I see is: Where do you get $currentRowColor from? Was this
in your code too? Then this won't work ... as David already said. The
problem: You won't get a variable value from using a template once to the
template using it the 2nd time (with easy <xsl:apply-templates
select="row"/>). One method would be using recursive template: Apply always
only the next following-sibling one. So:

<xsl:template match="table">
    <table>
        <xsl:apply-templates select="row[1]"/>
    </table>
</xsl:template>

<xsl:template match="row">
    <xsl:param name="color-of-last-row"/>
    <xsl:variable name="color-of-this-row">
        <xsl:choose>
            <xsl:when test="@t_orno != preceding-sibling::row[1]/@t_orno">
                <xsl:choose>
                    <xsl:when test="$color-of-last-row='#EFFFFF'">
                        <xsl:text>#FFFFFF</xsl:text>
                    </xsl:when>
                    <xsl:otherwise>
                        <xsl:text>#EFFFFF</xsl:text>
                    </xsl:otherwise>
                </xsl:choose>
            </xsl:when>
            <xsl:otherwise>
                <xsl:value-of select="$color-of-last-row"/>
            </xsl:otherwise>
        </xsl:choose>
    </xsl:variable>
    <tr bgcolor="{$color-of-this-row}">
        <!-- filling the <tr> with some <td>s -->
    </tr>
    <xsl:apply-templates select="following-sibling::row[1]">
        <!-- give the $color-of-this-row as color-of-last-row to the next
row -->
        <xsl:with-param name="color-of-last-row" select="$color-of
this-row"/>
    </xsl:apply-templates>
</xsl:template>

This should solve the problem - if this is the problem you had.
