NodeType

Table.NodeType property

Returns Table.

public override NodeType NodeType { get; }

Shows how to traverse a composite node’s tree of child nodes.

    // Any node that can contain child nodes, such as the document itself, is composite.
    Assert.True(doc.IsComposite);

    TraverseAllNodes(doc, 0);

/// with an indent depending on depth as well as the contents of all inline nodes.

        // Recurse into the node if it is a composite node. Otherwise, print its contents if it is an inline node.

        else
        {
