How could I use ruby to extract information from a table consisting of these rows? Is it possible to detect the comments using nokogiri?

```
<!-- Begin Topic Entry 4134 --> 
    <tr> 
        <td align="center" class="row2"><image src='style_images/ip.boardpr/f_norm.gif' border='0'  alt='New Posts' /></td>
