Re: How to get currently selected tab index and its content

You are almost there.. You can get the Tab's document from the tabnode
(your domnode i assume) like this

	:
nodeList->Item(i, getter_AddRefs(domNode));


nsCOMPtr<nsIDOMXULElement> xulElement = do_QueryInterface(domNode);

nsCOMPtr<nsIBoxObject> boxObject;
xulElement->GetBoxObject( getter_AddRefs(boxObject);

nsCOMPtr<nsIBrowserBoxObject> browserObj = do_QueryInterface(boxObject);

nsCOMPtr<nsIDocShell> docShell;
browserObj->GetDocShell( getter_AddRefs(docShell) );

nsCOMPtr<nsIDOMWindow> domWindow = do_GetInterface(docShell)

nsCOMPtr<nsIDOMDocument> doc;
domWindow->GetDocument( getter_AddRefs((spDoc) );

Remember to check return values and NULL pointers :)... Keep in mind
that some of the interfaces are unfrozen as well.

Let me know how it goes..

Cheers,
Jens
