reg expr help

Hello, I have a question about a regular expression

I am stripping some content out of a website,

I need to grab the text between 2 td tags, and the td tag has class="contentIwant"

The trouble is many of the pages also have another td with the same class,
as you can see below
-----

         <td class="contentIwant" height="8"><img src="images/spacer.gif" width="1" height="8"></td>
                                      </tr>
                                  </table></td>
                                </tr>
                            </table></td>
                          </tr>
                          <tr>
                            <td align="justify" class="contentIwant"><p><i>Jonathan Livingston Seagull</i> was one of the hits of the 1970s.  THIS IS THE TEXT I WANT</td>


Can some one help me please.
I have tried the following two RegExprs, but the both grab the <img src....   which I dont want

$found = preg_match('/class="gmatter3".*?>((.*\n)*?.*)<\/td>/', $the_page,$matches);

 $found = preg_match('/class="gmatter3".*?>(?!.img src)((.*\n)*?.*)<\/td>/', $the_page,$matches);


Thanks in advance
