Returns an unsigned short that will be used to tell if a given Node must be accepted or not by the NodeIterator or TreeWalker iteration algorithm.
Returns an unsigned short that will be used to tell if a given Node must be accepted or not by the NodeIterator or TreeWalker iteration algorithm. This method is expected to be written by the user of a NodeFilter. Possible return values are: Constant Description FILTER_ACCEPT Value returned by the NodeFilter.acceptNode() method when a node should be accepted. FILTER_REJECT Value to be returned by the NodeFilter.acceptNode() method when a node should be rejected. The children of rejected nodes are not visited by the NodeIterator or TreeWalker object; this value is treated as "skip this node and all its children". FILTER_SKIP Value to be returned by NodeFilter.acceptNode() for nodes to be skipped by the NodeIterator or TreeWalker object. The children of skipped nodes are still considered. This is treated as "skip this node but not its children".
MDN
A NodeFilter interface represents an object used to filter the nodes in a NodeIterator or TreeWalker. They don't know anything about the DOM or how to traverse nodes; they just know how to evaluate a single node against the provided filter.
