Re: [xsl] Counting following siblings for table spans

["Wendell Piez wapiez@xxxxxxxxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

Hello again,

Accumulators turned out to be a bit trickier than I thought, so I tried
sibling recursion, and this appears to work as well:

<xsl:template match="row/cell-1">
        <xsl:copy>
            <xsl:copy-of select="@*"/>
            <xsl:attribute name="rowspan" select="1"/>
            <xsl:attribute name="rowspan">
                <xsl:apply-templates select="../following-sibling::*[1]"
mode="rowspan">
                    <xsl:with-param name="c" select="1"/>
                </xsl:apply-templates>
            </xsl:attribute>
            <xsl:apply-templates/>
        </xsl:copy>
    </xsl:template>

    <xsl:template match="*[exists(cell-1)]" mode="rowspan" as="xs:integer">
        <xsl:param name="c" required="yes"/>
        <xsl:sequence select="$c"/>
    </xsl:template>

    <xsl:template match="*" mode="rowspan" as="xs:integer">
        <xsl:param name="c" required="yes"/>
        <xsl:if test="empty(following-sibling::*[1])">
            <xsl:sequence select="$c"/>
        </xsl:if>
        <xsl:apply-templates mode="rowspan"
select="following-sibling::*[1]">
            <xsl:with-param name="c" select="$c + 1"/>
        </xsl:apply-templates>
    </xsl:template>

Regards, Wendell
