How to split table after certain number of columns

1.4k views Asked by At

I have a little issue that I've been struggling with for a couple of days now.

Here is input xml:

<Facture>
    <Mensualite>
        <Lines>
            <Line>
                <NumeroMensualite>1</NumeroMensualite>
                <AnneeEcheance>2015</AnneeEcheance>
                <DateEcheance>20150618</DateEcheance>
                <Montant>163.14</Montant>
            </Line>
            <Line>
                <NumeroMensualite>2</NumeroMensualite>
                <AnneeEcheance>2015</AnneeEcheance>
                <DateEcheance>20150718</DateEcheance>
                <Montant>120</Montant>
            </Line>
            <Line>
                <NumeroMensualite>3</NumeroMensualite>
                <AnneeEcheance>2015</AnneeEcheance>
                <DateEcheance>20150818</DateEcheance>
                <Montant>120</Montant>
            </Line>
            <Line>

            </Line>
        </Lines>
    </Mensualite>

And here is the xslfo that i've created:

I need to split the table if the xml contains more then 12 Lines (columns in that case) and make a new table after. I'm a bit stuck on it and it's really frustrating. Does anyone have any pointers?

I couldn't understand your XSLT.

To simplify the matter to the question of creating a separate table for every N lines, where each line forms a column, consider the following stylesheet:

XSLT 1.0

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>

<xsl:variable name="col-limit" select="5" />
<xsl:variable name="rows" select="/Facture/Mensualite/Lines/Line[1]/*" />

<xsl:template match="/Facture">
    <root>
        <xsl:apply-templates select="Mensualite/Lines/Line[position() mod $col-limit = 1]" />
    </root>
</xsl:template>

<xsl:template match="Line">
    <xsl:variable name="cols" select=". | following-sibling::Line[position() &lt; $col-limit]"/>
    <table border="1">
        <xsl:for-each select="$rows">
        <xsl:variable name="row" select="position()"/>
            <tr>
                <th><xsl:value-of select="name()"/></th>
                <xsl:apply-templates select="$cols/*[$row]"/>
            </tr>
        </xsl:for-each>
    </table>
</xsl:template> 

<xsl:template match="Line/*">
    <td><xsl:value-of select="."/></td>
</xsl:template> 

</xsl:stylesheet>

When applied to your example input, the result (rendered) will be:
