Choose a parent base on which node is used to iterate over children nodes. This leads to duplicate handing of child nodes. A node will be handled so many times how many parents it has. For example: p1 p2 \ / c Will be handled as: p1 p2 | | c c If c has children they will be handled X times c is handled.
