XmlDocument^ document = gcnew XmlDocument();
document->Load("contosoBooks.xml");
XPathNavigator^ navigator = document->CreateNavigator();

navigator->MoveToChild("bookstore", "http://www.contoso.com/books");
navigator->MoveToChild("book", "http://www.contoso.com/books");

注解

若要创建新元素节点,请在 XML 字符串参数中包含所有 XML 语法。 新 book 节点的字符串为 InsertAfter("<book/>")。 在当前节点的文本节点为 InsertAfter("book")后插入文本“book”的字符串。 如果 XML 字符串包含多个节点,则添加所有节点。

以下是使用 InsertAfter 该方法时要考虑的重要说明。
