NodeType

Table.NodeType property

Returns Table.

public override NodeType NodeType { get; }

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

public void RecurseChildren()

    Document doc = new Document(MyDir + "Paragraphs.docx");

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

    // Invoke the recursive function that will go through and print all the child nodes of a composite node.
    TraverseAllNodes(doc, 0);

/// <summary>
/// Recursively traverses a node tree while printing the type of each node
/// 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.
        if (childNode.IsComposite)
        {
            Console.WriteLine();
            TraverseAllNodes((CompositeNode)childNode, depth + 1);

        else
        {
            Console.WriteLine();

Shows how to find out if a tables are nested.

    }
