previous_node method

previous_node

Moves the TreeWalker to the previous visible node in document order relative to the current node, and returns the new node. If the current node has no previous node, or if the search for previousNode attempts to step upward from the TreeWalker’s root node, returns null, and retains the current node.

Returns

The new node, or null if the current node has no previous node in the TreeWalker’s logical view.
