    You can reference the parent either by using parent or using the top variable that always points to the outer most document.

    • parent == parent window
    • top == out most window

    So for accesing the first div in the parent window

    var d = parent.document.getElementsByTagName("div")[0];
    

    But as noted already in the comment, both the outer document and the document in the iframe need to be from the same domain or you will be blocked for security reasons.
