Accessing XUL anonymous content using C++

[Vaibhav]

Hi All,

I am writing Firefox extension using C++.
I am trying to access XUL:tabox element in "TabOpen" event handler,
but I am unable access any XUL element.

I am putting here pseudocode of my extension for reference:

HandleEvent()
{
if (event type is TabOpen)
{
nsCOMPtr<nsIDOMNode> OriginalNode = do_QueryInterface(event-
>GetTarget);
nsCOMPtr<nsIDOMNodeList> childlist;

//
// Note here that I got OriginalNode's local name as
"tabbrowser"
//

OriginalNode->GetChildNodes(getter_AddRefs(childlist));
PRUint32 len;
childlist->GetLength(&len); // Return 1; consider only "popup" child
element.

nsString localName;
nsCOMPtr<nsIDOMNode> node1;
childlist->Item(0, getter_AddRefs(node1));
node1->GetLocalName(localName); // Returns "popup" as the local
name.
}
}

By traversing the DOM tree through DOM Inspector, I came to know that
XUL elements are anonymous content.

How do I access these XUL elements?

Very Thanks in advance,

Vaibhav.
