XSLT Generate Dynamic Rows and Columns for Apache FOP

问题

For the following xml file, i need to generate an xsl-fo file to be converted into pdf.

I am new to style sheets and struggling to create dynamic table. Please help.

Also, the width for each column varies,based on the column.How would i include this into the code?

The Column Headers and Column Values are dynamically populated in the xml file. Below is a sample.

Can anybody please help in generating xsl-fo or xslt code?

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ReportData>

    <ColumnHeaders>
       <ColumnHeader>
           <Name>Col-Header1</Name>
           <Width>5</Length>
       </ColumnHeader>
       <ColumnHeader>
           <Name>Col-Header2</Name>
           <Width>10</Length>
       </ColumnHeader>
       <ColumnHeader>
           <Name>Col-Header3</Name>
           <Width>8</Length>
        </ColumnHeader>
    </ColumnHeaders>

<Rows>
       <Row>
          <Column>Row1-Col1</Column>
          <Column>Row1-Col2</Column>
          <Column>Row1-Col3</Column>              
       </Row>
       <Row>
          <Column>Row2-Col1</Column>
          <Column>Row2-Col2</Column>
          <Column>Row2-Col3</Column>
       </Row>
    </Rows>
</ReportData>

This should get you started. I used cm for the column width and the page is 11" x 8.5" (landscape) so the table would fit on the page. This should be easy for you to change.

XML Input (fixed to be well-formed)

<ReportData>

        </ColumnHeader>
        <ColumnHeader>
            <Name>Col-Header2</Name>
            <Width>10</Width>
        </ColumnHeader>
        <ColumnHeader>
            <Name>Col-Header3</Name>
            <Width>8</Width>
        </ColumnHeader>
    </ColumnHeaders>

    <Rows>
        <Row>
