[jQuery] find table rows that contains text

[Sridhar]

Hi,

   I am trying to get a reference to a table row that contains an
exact match of a text. But I am getting more than one row. can you
please help me? Following is the html table structure and the jquery
script.
-- html
<table>
   <tr>
       <td><a>063</a></td>
   </tr>
   <tr>
       <td><a>63</a></td>
   </tr>
</table>

-- script
var rows = $('table tr:contains(' + "'" + '63' + "'" + ')');

as you can see, both the rows contain text 63. But I want to get the
reference to second row since that contains the exact match. How would
I do that?

Thanks,
sridhar.
