Examples

Shows how to process absolute position tab characters with a document visitor.

    auto doc = MakeObject<Document>(MyDir + u"Absolute position tab.docx");

    // Extract the text contents of our document by accepting this custom document visitor.
    auto myDocTextExtractor = MakeObject<ExAbsolutePositionTab::DocTextExtractor>();
    doc->get_FirstSection()->get_Body()->Accept(myDocTextExtractor);

    // The absolute position tab, which has no equivalent in string form, has been explicitly converted to a tab character.
    ASSERT_EQ(u"Before AbsolutePositionTab\tAfter AbsolutePositionTab", myDocTextExtractor->GetText());

    // An AbsolutePositionTab can accept a DocumentVisitor by itself too.
    auto absPositionTab =
        System::ExplicitCast<AbsolutePositionTab>(doc->get_FirstSection()->get_Body()->get_FirstParagraph()->GetChild(NodeType::SpecialChar, 0, true));
