NodeIterator
The NodeIterator interface represents an iterator over the members of a list of the nodes in a subtree of the DOM. The nodes will be returned in document order.
A NodeIterator can be created using the Document.createNodeIterator() method.

This operation is a no-op. It doesn't do anything. Previously it was telling the engine that the NodeIterator was no more used, but this is now useless.

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

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 first call to nextNode() returns the first node in 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.

Concrete fields
Returns an unsigned long being a bitmask made of constants describing the types of Node that must to be presented. Non-matching nodes are skipped, but their children may be included, if relevant. The possible values are: Constant Numerical value Description NodeFilter.SHOW_ALL -1 (that is the max value of unsigned long) Shows all nodes. NodeFilter.SHOW_ATTRIBUTE 2 Shows attribute Attr nodes. This is meaningful only when creating a NodeIterator with an Attr node as its root; in this case, it means that the attribute node will appear in the first position of the iteration or traversal. Since attributes are never children of other nodes, they do not appear when traversing over the document tree. NodeFilter.SHOW_CDATA_SECTION 8 Shows CDATASection nodes. NodeFilter.SHOW_COMMENT 128 Shows Comment nodes. NodeFilter.SHOW_DOCUMENT 256 Shows Document nodes. NodeFilter.SHOW_DOCUMENT_FRAGMENT 1024 Shows DocumentFragment nodes. NodeFilter.SHOW_DOCUMENT_TYPE 512 Shows DocumentType nodes. NodeFilter.SHOW_ELEMENT 1 Shows Element nodes. NodeFilter.SHOW_ENTITY 32 Shows Entity nodes. This is meaningful only when creating a NodeIterator with an Entity node as its root; in this case, it means that the Entity node will appear in the first position of the traversal. Since entities are not part of the document tree, they do not appear when traversing over the document tree. NodeFilter.SHOW_ENTITY_REFERENCE 16 Shows EntityReference nodes. NodeFilter.SHOW_NOTATION 2048 Shows Notation nodes. This is meaningful only when creating a NodeIterator with a Notation node as its root; in this case, it means that the Notation node will appear in the first position of the traversal. Since entities are not part of the document tree, they do not appear when traversing over the document tree. NodeFilter.SHOW_PROCESSING_INSTRUCTION 64 Shows ProcessingInstruction nodes. NodeFilter.SHOW_TEXT 4 Shows Text nodes.
