I have created a browser application. The application works as follows.

The user clicks a link on the left ;This action is hrefed to a another htm page(b) that has two inlined frame one of which is disabled. So basically another htm page(c) opens up in the visible inlined frame.

The page b has two sub tabs at the top. On clicking the first subtab page c comes up and on clicking another subtab page d comes up in the so called hidden frame that gets enabled on clicking subtab2.
.
The application has the functionality to build the DOM for the parent frame housing page a. The problem is to get the DOM for the two child frames(one of which is hidden) that houses htm pages c and d. The parent DOM does not have any of the HTML elements of the child frame.
Can anyone tell me whow to get the DOM for the child frame. By gettign this the application is going to have access to the child frame HTML elements id which it is currently not able to get.

The parentframe.childframe.formname.elementname thing is ruled out according to teh requirement.
