Shows how to filter specific types of document elements when making a comparison.
// Create the original document, and populate it with various kinds of elements.
Document docOriginal = new Document();
DocumentBuilder builder = new DocumentBuilder(docOriginal);

// Paragraph text referenced with an endnote:
builder.Writeln("Hello world! This is the first paragraph.");
builder.InsertFootnote(FootnoteType.Endnote, "Original endnote text.");

// Table:
builder.StartTable();
builder.InsertCell();
builder.Write("Original cell 1 text");
builder.InsertCell();
builder.Write("Original cell 2 text");
builder.EndTable();

// Textbox:
Shape textBox = builder.InsertShape(ShapeType.TextBox, 150, 20);
builder.MoveTo(textBox.FirstParagraph);
builder.Write("Original textbox contents");

// DATE field:
builder.MoveTo(docOriginal.FirstSection.Body.AppendParagraph(""));
builder.InsertField(" DATE ");

// Comment:
Comment newComment = new Comment(docOriginal, "John Doe", "J.D.", DateTime.Now);
newComment.SetText("Original comment.");
builder.CurrentParagraph.AppendChild(newComment);

// Header:
builder.MoveToHeaderFooter(HeaderFooterType.HeaderPrimary);
builder.Writeln("Original header contents.");

// Create a clone of our document, and perform a quick edit on each of the cloned document's elements.
Document docEdited = (Document)docOriginal.Clone(true);
