Hi, all

I am trying to write a template that will generate a table based on a xml
file and right now I don't have any
clue how to do it.

If I have a source file looks like this

<foo>
      <bar id='1'>
              <someElement>a</someElement>
      </bar>
      <bar id='2'>
              <someElement>b</someElement>
      </bar>
      <bar id='3'>
              <someElement>c</someElement>
      </bar>
      <bar id='4'>
              <someElement>d</someElement>
      </bar>
      <bar id='5'>
              <someElement>e</someElement>
      </bar>
      ...
</foo>

Can I write a style sheet that will transform the source file above to a
html table like this?

<table>
      <tr>
              <td>a</td>
              <td>b</td>
              <td>c</td>
      </tr>
      <tr>
              <td>d</td>
              <td>e</td>
              <td>&nbsp;</td>
      </tr>
      ...
</table>

Basicly, I want to generate N columns per row but I don't know how many
"bar"s I have in the source file.

Select all bar elements for processing.
In the template that matches a bar element, if position() returns
a value that when divided by 3 has a remainder of 1, generate a table row
element. Inside that element, create cells for the current node and its
first two following siblings.
