NodeFilter

Available on js

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.

Methods

`acceptNode (node:Node):Int`

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. For `TreeWalker`, child nodes are also rejected. For `NodeIterator`, this flag is synonymous with FILTER_SKIP.
`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".
