Disabling Links

[John Stewart]

I am trying to figure out a way to disable links in my embedded app, and
I have been unsuccessful. After some investigation, I would have thought
the following code snippet to be a solution to my problem:

    nsCOMPtr<nsIDOMHTMLDocument> domdoc;
    rv = doc->QueryInterface(nsIDOMHTMLDocument::GetIID(),
                             getter_AddRefs(domdoc));

    if (NS_FAILED(rv)) return;

    nsCOMPtr<nsIDOMHTMLCollection> links;
    domdoc->GetLinks(getter_AddRefs(links));

    PRUint32 numnodes;
    links->GetLength(&numnodes);

    nsCOMPtr<nsIDOMNode> link;
    for (unsigned int i = 0; i < numnodes; i++)
    {
        // The following line does not produce the correct result. The
elements in the
        // collection are of the type nsIDOMHTMLAnchorElement...
        nsCOMPtr<nsIDOMHTMLLinkElement>     alink =
(do_QueryInterface(link));

        alink->SetDisabled(FALSE);
    }

If anyone knows of a solution to this problem, I would appreciate
hearing from you. Thanks.
