I want to select only the first level of 'td' elements in a table and not the cells of any nested tables. eg:

<table id="Outer">
    <tr>

        <td> --this one
        </td> 

        <td> --this one
            <table>
                <tr>
                    <td></td> -- but not this one or any deeper nested cells
                </tr>
            </table>
        </td>

    </tr> 
</table>

(and yes in prod code i would include tbody, thead...)

A: 

Give the outermost table an id of "Outer":

$("table#Outer > td").text("selected");
Plan B
didn't seem to work for me

TD is not an immediate child of a TABLE.

you have to do $("table#Outer > tbody > tr > td").text("selected"); even if i don't have tbody in my source the browser seems to put it in automatically (FF3)

+7  A: 

I'd use the children selector, which only selects the immediate children matching the expression. To make it easy to select just the outer table, I'd give it a name. NOTE: this won't work with your sample as I've added in the selectors for thead, tbody, and tfoot as you indicate you will have in production. Adjust accordingly for your sample.

$('table#namedTable').children('tbody,thead,tfoot')
                     .children('tr')
                     .children('td')

perfect, thanks!

oddly enough the browser automatically added tbody (FireFox) and so the code did work even if i didn't have tbody in the source.

+1, excellent answer - On first glance, this problem seems quite trivial, but that's not the case.
