Examples
Shows how to implement custom logic over node insertion in the document by changing the font of inserted HTML content.
public void TestNodeChangingInDocument()
{
    // Create a blank document object
    Document doc = new Document();
    DocumentBuilder builder = new DocumentBuilder(doc);

    // Set up and pass the object which implements the handler methods.
    doc.NodeChangingCallback = new HandleNodeChangingFontChanger();

    // Insert sample HTML content
    builder.InsertHtml("<p>Hello World</p>");

    doc.Save(ArtifactsDir + "Document.FontChanger.doc");

    // Check that the inserted content has the correct formatting
    Run run = (Run) doc.GetChild(NodeType.Run, 0, true);
    Assert.AreEqual(24.0, run.Font.Size);
    Assert.AreEqual("Arial", run.Font.Name);
}

public class HandleNodeChangingFontChanger : INodeChangingCallback
{
    // Implement the NodeInserted handler to set default font settings for every Run node inserted into the Document
    void INodeChangingCallback.NodeInserted(NodeChangingArgs args)
    {
        // Change the font of inserted text contained in the Run nodes.
        if (args.Node.NodeType == NodeType.Run)
        {
            Aspose.Words.Font font = ((Run) args.Node).Font;
            font.Size = 24;
            font.Name = "Arial";
        }
    }

    void INodeChangingCallback.NodeInserting(NodeChangingArgs args)
    {
        // Do Nothing
    }

    void INodeChangingCallback.NodeRemoved(NodeChangingArgs args)
    {
        // Do Nothing
    }

    void INodeChangingCallback.NodeRemoving(NodeChangingArgs args)
    {
        // Do Nothing
    }
