I have a <Table> with no ID and a <TD> with no ID and I have the following I need to be able to get the value from. I did not write the HTML nor can I change it, I'm using grease monkey on FF so I can make some changes to a website.

<td>157</td>

You can use something like this:

var arrCells = document.getElementsByTagName('td');
for (idx=0;idx<arrCells.length;idx++) {
  strValue = arrCells[idx].innerHTML;
  alert(strValue);
}

The problem is this will give you the contents of every TD element on the page. You would need some identifiable property to distinguish which one you are looking for.

Use something like this in your jscript code.
var elTableCells = elTableRow.getElementsByTagName("td");
alert(elTableCells[0].innerText);

flips I think that will do the trick because it will always be 11th in spot

if (idx==11){
   alert(strValue);
}

Thanks
