Why not use jQuery? You won't have to walk the entire DOM. You just specify the object ID and jQuery finds it for you.

>loDiv=window.parent.document.createElement("div") 
>window.parent.document.body.appendChild(loDiv)

>But, this is not totally the right syntax as loDiv has been created in an IFrame inside the main window. The main window do have a variable available such as:
>

>loDiv=""

>So, I guess, once the appendChild() is done, I need to assign that loDiv to the loDiv of the main window. I am not sure about the proper syntax however.
