NodeIterator

The NodeIterator.filter read-only property returns a NodeFilter object, that is an object which implements an acceptNode(node) method, used to screen nodes.

The NodeIterator.pointerBeforeReferenceNode read-only property returns a boolean flag that indicates whether the NodeFilter is anchored before (if this value is true) or after (if this value is false) the anchor node indicated by the A boolean.

The NodeIterator.referenceNode read-only property returns the iterator remains anchored to the reference node as specified by this property.

The NodeIterator.root read-only property represents the traverses.

The NodeIterator.whatToShow read-only property represents an unsigned integer representing a bitmask signifying what types of nodes should be returned by the NodeIterator.

The NodeIterator.nextNode() method returns the next node in the set represented by the NodeIterator and advances the position of the iterator within the set.

The NodeIterator.previousNode() method returns the previous node in the set represented by the NodeIterator and moves the position of the iterator backwards within the set.
