Document.CreateTreeWalker

CreateTreeWalker(Node)

Create a new TreeWalker over the subtree rooted at the specified node.

public ITreeWalker CreateTreeWalker(Node root)
ParameterTypeDescription
rootNodenode 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.

Return Value

The newly created TreeWalker.

Exceptions

exceptioncondition
DOMExceptionNOT_SUPPORTED_ERR: Raised if the specified root is null.

CreateTreeWalker(Node, long)

Create a new TreeWalker over the subtree rooted at the specified node.

public ITreeWalker CreateTreeWalker(Node root, long whatToShow)
ParameterTypeDescription
rootNodenode 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.
whatToShowInt64flag specifies which node types may appear in the logical view of the tree presented by the tree-walker. See the description of NodeFilter for the set of possible SHOW_ values.These flags can be combined using OR.

Return Value

The newly created TreeWalker.

Exceptions

exceptioncondition
DOMExceptionNOT_SUPPORTED_ERR: Raised if the specified root is null.
