public function createNodeIterator(root:Node, whatToShow:Number, filter:NodeFilter, entityReferenceExpansion:Boolean):NodeIterator| Product Versions : |  5.5 6.0 7.0 8.0 as IE7 8.0 as IE8  2.0 3.0 3.5  3.0 3.1 4.0b  1.0 2.0  9.62 10.0a |
| Introduced in: | DOM 2 Core |
Create a new NodeIterator over the subtree rooted at the specified node.
Parameters
root:Node — The node which will be iterated together with its children. The iterator is initially positioned
just before this node. The whatToShow flags and the filter, if any, are not considered when setting this position. The root must not be null.
| |
whatToShow:Number — This flag specifies which node types may appear in the logical view of the tree presented
by the iterator. These flags can be combined using OR.
| |
filter:NodeFilter — The NodeFilter to be used with this TreeWalker, or null to indicate no filter.
| |
entityReferenceExpansion:Boolean — The value of this flag determines whether entity reference nodes are expanded.
|
NodeIterator — The newly created NodeIterator.
|
DOMException — NOT_SUPPORTED_ERR: Raised if the specified root is null.

}| DOM 2 TR createTreeWalker | () | method |
public function createTreeWalker(root:Node, whatToShow:Number, filter:NodeFilter, entityReferenceExpansion:Boolean):TreeWalker| Product Versions : | 5.5 6.0 7.0 8.0 as IE7 8.0 as IE8 2.0 3.0 3.5 3.0 3.1 4.0b 1.0 2.0 9.62 10.0a |
| Introduced in: | DOM 2 Core |
Create a new TreeWalker over the subtree rooted at the specified node.
Parameters
root:Node — The node which will serve as the root for the TreeWalker. The whatToShow flags and the NodeFilter
are not considered when setting this value; any node type will be accepted as the root. The currentNode of the
TreeWalker is initialized to this node, whether or not it is visible. The root functions as a stopping point for
traversal methods that look upward in the document structure, such as parentNode and nextNode. The root must not
be null.
| |
whatToShow:Number — This flag specifies which node types may appear in the logical view of the tree presented by
the tree-walker. These flags can be combined using OR.
| |
filter:NodeFilter — The NodeFilter to be used with this TreeWalker, or null to indicate no filter.
| |
entityReferenceExpansion:Boolean — If this flag is false, the contents of EntityReference nodes are not presented in the logical view.
|
TreeWalker — The newly created TreeWalker.
|
DOMException — NOT_SUPPORTED_ERR: Raised if the specified root is null.
