I *think* the following will get you started:

$("#veh_odometer").children("tr").each( function () {
 //'this' refers to the current tr
 var address = $("td:eq(2)", this).text();
 console.log("VALUE: " + address);
 // note: console.log works in Firefox.
 // Substitue an alert if desired

 // . . . Other processing here . . .
});

Two points here though:

- The $("#veh_odometer").children("tr") bit can be done in a few different
ways.  But this should work (unless the the tbody element is needed too...).
For instance you can say $("#veh_odometer > tbody > tr").each() for
effectively the same results.... experiement for the method that works best
for you.

- the var address line.  We are using a "context" reference here - we are
saying give me the third TD in the context of the current row (this).  Again,
more than one way to do this...  $(this).children("td:eq(2)") would do the
same ( I think ).

Anyways, hope that helps.
