I have two questions.
1) I cannot find where must I write the register of the filter
2) I have a structure like this:
(caption1, caption2, caption3, caption4)
(a,b,c,d)
I want to print it like:
<table>
<tr><td>Caption1</td><td>A</td></tr>
<tr><td>Caption2</td><td>B</td></tr>
<tr><td>Caption3</td><td>C</td></tr>
<tr><td>Caption4</td><td>D</td></tr>
How can I do that? It seems a bit different than your, because you don't have
captions...
