[General jQuery] Script targeting only following ID

[General jQuery] Script targeting only following ID

Hi!
 
I have following little script that applies to my entire html page:
  1. $("td[id*='MSOZoneCell_WebPartWPQ']>table>tbody>tr>td").each
    (
            function()
                {


  2.             }
    });
I want to target only elements contained in a certain <div id="myID"></div>.
Is that possible? And how can I do it?
 
Thanks in advance for your help.
Best Regards,
