[jQuery] Problem in [] filter

[matifibrahim]

//
$(document).ready(function() {
$('th').parent().addClass('table-heading');
$('tr:not([th]):even').addClass('even');
$('tr:not([th]):odd').addClass('odd');
$('td:contains("Henry")').addClass('highlight');
});
//

It is supposed to add 'even' and 'odd' classes to odd and even number
of rows of a table EXCEPT TABLE HEADER, but unfortunaley it is not
working as it should because it also formates the heading (attaching
'even' class to table header and I can see it in firebug). It looks
that the filter '[th]' is not working. Tested both on FF and IE, same
problem on both. Is it something wrong with [th]? Any recommendation?
One more thing, I also tried it with 'jquery-1.2.2.js', but the same
problem. Thanks in advance..
