Abstract
A method and apparatus for identifying a keyboard inaccessible node on a web page. The method may include acquiring all nodes in a DOM tree of the web page; identifying a mouse operable node among all the nodes; checking whether or not said mouse operable node is keyboard navigable and whether or not said mouse operable node is keyboard operable; and extracting the keyboard non-navigable node and the keyboard inoperable node as said keyboard inaccessible node.
