IDOMTreeWalker interface
Provides an object that can be used to traverse a filtered hierarchy of nodes or elements in a document. This interface is ideal for navigating a representation of the document's tree structure. The IDOMTreeWalker is dynamic and reflects the state of the document as it is edited or changed.
Members
The IDOMTreeWalker interface inherits from the IDispatch interface. IDOMTreeWalker also has these types of members:
- Methods

Methods
The IDOMTreeWalker interface has these methods.
| Method | Description |
|---|---|
| firstChild | Retrieves a reference to the first child of the current node of the filtered TreeWalker hierarchy and updates IDOMTreeWalker::currentNode. |
| lastChild | Retrieves a reference to the last child of the current node of the filtered TreeWalker hierarchy and updates IDOMTreeWalker::currentNode. |
| nextNode | Returns the next node in the NodeIterator or TreeWalker list and updates IDOMTreeWalker::currentNode. |
| nextSibling | Retrieves the next sibling of the current node in the filtered TreeWalker hierarchy and updates IDOMTreeWalker::currentNode. |
| parentNode | Retrieves the parent object in the document hierarchy relative to the current node and updates IDOMTreeWalker::currentNode. |
| previousNode | Returns the previous node in the NodeIterator or TreeWalker list and updates IDOMTreeWalker::currentNode. |
| previousSibling | Retrieves the previous sibling of the current node in the filtered TreeWalker hierarchy and updates IDOMTreeWalker::currentNode. |
Properties
The IDOMTreeWalker interface has these properties.
| Property | Description |
|---|---|
Sets or retrieves where the current node in a filtered TreeWalker hierarchy is positioned. |
|
Flag to specify whether or not the children of entity reference nodes are visible. |
|
Gets the function object that the iterator uses to filter nodes that go into TreeWalker hierarchies or NodeIterator lists. |
|
Gets the root node that was specified when the object was created. |
|
Gets which node types are presented through the iterator. Nodes that are not accepted are skipped, but their children are still considered. |
