document. When accessibility is turned on in Gecko, there is an nsIAccessibleDocument for each document whether it is XUL, HTML or whatever.
nsISupports
Last changed in Gecko 2.0 (Firefox 4 / Thunderbird 3.3 / SeaMonkey 2.1)You can QueryInterface to nsIAccessibleDocument from the nsIAccessible or nsIAccessNode for the root node of a document. You can also get one from nsIAccessNode.GetAccessibleDocument() or nsIAccessibleEvent.GetAccessibleDocument()

Methods
getAccessibleInParentChain()
Returns the first accessible parent of a DOM node. Guaranteed not to return null if the DOM node is in a document.
nsIAccessible getAccessibleInParentChain( in nsIDOMNode aDOMNode, in boolean aCanCreate );
Parameters
aDOMNode- The DOM node we need an accessible for.
aCanCreate- If
true, this method can create a new accessible. Otherwise, it will return the first cached accessible in the parent chain.
Return value
The first nsIAccessible found by crawling up the DOM node to the document root.
getCachedAccessNode
Obsolete since Gecko 2.0 (Firefox 4 / Thunderbird 3.3 / SeaMonkey 2.1)
This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.
Returns the access node cached by this document.
nsIAccessNode getCachedAccessNode( in voidPtr aUniqueID );
Parameters
aUniqueID- The unique ID used to cache the node. This matches up with the uniqueID attribute on
nsIAccessNode.
Return value
The nsIAccessNode cached for this particular unique ID.
getNameSpaceURIForID()
The namespace for each ID that is handed back.
AString getNameSpaceURIForID( in short nameSpaceID );
Parameters
nameSpaceID- The ID of the name space.
Return value
The name space for given ID.
