JQuery :: How To Select TR Inside Another Table

I am trying to hide aTRthat does not have id or class.
Example:
<table><tr><td>
<table><tr><td>
<table><tr>
<td>xxx</td><td class="SOMECLASS">SOMETEXT</td>
</tr><tr>
<td>yyy</td><td class="SOMECLASS"></td>
</tr></table></td></tr>
</table></td></tr>
</table>

The row contains a TD with class Some Class and contains some text Some Text. I tried this:
$("tr:has(:contains('SOMETEXT').SOMECLASS)").hide();
My problem is that the page has many nested tables and rows containing rows,so the selector above is true for all the TR's on the page and almost the whole pages is hidden. How can one change the selector to focus only on the row I am interested in?
