Protected Member Functions

virtual Node * GetFirst ()
 Identical to Node::DocFindFirstDepthFirst but skips over hidden nodes. NB. the first node in the document tree is guaranteed to never be hidden.
virtual Node * GetNext (Node *)
 Identical to Node::DocFindNextDepthFirst but skips over hidden nodes. To be precise, it doesn't follow child links for NodeHiddens.
