why do you need to test that?

if you get the foobar element by id. then get all of the link elements which are descendants of that, there is no need to test for that condition since you already know they are descendants of the foobar element.

Hank,
  Take another look at the code in http://#a24329247, the first lookup finds the "foobar" div.  The next only locates anchor tags within this div.

Hank, thanks for the grade & points, but I think that alien109 deserves them because he did the referenced update.

Please "request assistance" with this question, and give alien109 all the points.

Thanks
