XML Table to Html

JohnBampton · March 9th, 2009, 08:22 AM

I have got this table in xml format below, where the tcols trows and ccols crows attributes all specify number of table columns, number of table rows, table cell colspans and table cell rowspans. Now I had the XSL to convert this xml table to a standard html table working until I came across the table cell rowspan (crows) greater than one. Attached is my XSL as well, any suggestions on this, as I know that my code doesn't accomodate rowspans??

Code:

<?xml version="1.0" encoding="UTF-8"?>
<Root>
    <TABELLA data_mod="2008-10-30 12:20:59" id="2899" locale="it_IT" colonne="3" righe="2"
        colonna_1="33%" colonna_2="33%" colonna_3="33%">
        <grown>
            <TAB_2899>
                <story>
                    <Table xmlns:aid="http://ns.adobe.com/AdobeInDesign/4.0/" aid:table="table"

                        <Cell aid:table="cell" aid:crows="2" aid:ccols="1" aid:ccolwidth="184"
                            larghezza="33%">
                            row 1 col 1
                        </Cell>
                        <Cell aid:table="cell" aid:crows="1" aid:ccols="1" aid:ccolwidth="184"
                            larghezza="33%">
                            row 1 col 2
                        </Cell>
                        <Cell aid:table="cell" aid:crows="1" aid:ccols="1" aid:ccolwidth="184"
                            larghezza="33%">row 2 col 2</Cell>
                        <Cell aid:table="cell" aid:crows="1" aid:ccols="1" aid:ccolwidth="184"
                            larghezza="33%">row 2 col 2</Cell>
                        <Cell aid:table="cell" aid:crows="1" aid:ccols="1" aid:ccolwidth="184"
                            larghezza="33%">row 2 col 2</Cell>
                    </Table>
                </story>
            </TAB_2899>
        </grown>
    </TABELLA>
</Root>

I have got the number of rows right its just the rowspan. Please enlighten me!

This kind of problem certainly isn't easy. I think a general solution involves building an expanded version of the table in which there's an entry for each (1x1) unit cell, which means expanding a rowspan or colspan to a number of unit cells; perhaps in this expanded version each unit cell can contain a reference to the top-left corner of the larger original cell in which it is contained. But the details depend on exactly what you want to do.

I knew it was a hard problem, thankful that you said that.

Actually its not my problem, I have been helping someone else on another forum http://forums.tizag.com/showthread.php?t=12139
and they give me a sample table and each time I solve the problem and the XSL code gets a bit harder, then they give me a more complex table.

At the moment I am one step ahead of them thinking about the cell rowspan as I can see that they will come back to me with a table with this in it.

Anyway if I find the solution which I doubt, i will post it.

Thanks.
