Examples

Shows how to print the node structure of every header and footer in a document.

public void HeaderFooterToText()
{
    Document doc = new Document(MyDir + "DocumentVisitor-compatible features.docx");
    HeaderFooterStructurePrinter visitor = new HeaderFooterStructurePrinter();

    // When we get a composite node to accept a document visitor, the visitor visits the accepting node,
    // and then traverses all the node's children in a depth-first manner.
    // The visitor can read and modify each visited node.
    doc.Accept(visitor);

    Console.WriteLine(visitor.GetText());

    // An alternative way of accessing a document's header/footers section-by-section is by accessing the collection.
    HeaderFooter[] headerFooters = doc.FirstSection.HeadersFooters.ToArray();
    Assert.AreEqual(3, headerFooters.Length);
