Exemples

Dans l’exemple suivant, les premiers et deuxième book éléments du fichier sont remplacés par un nouvel élément vide book à l’aide contosoBooks.xml de la ReplaceRange méthode.

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

XmlNamespaceManager^ manager = gcnew XmlNamespaceManager(document->NameTable);
manager->AddNamespace("bk", "http://www.contoso.com/books");

XPathNavigator^ first = navigator->SelectSingleNode("/bk:bookstore/bk:book[1]", manager);
XPathNavigator^ last = navigator->SelectSingleNode("/bk:bookstore/bk:book[2]", manager);

navigator->MoveTo(first);
XmlWriter^ newRange = navigator->ReplaceRange(last);
newRange->WriteStartElement("book");
    newRange->WriteAttributeString("genre", "");
    newRange->WriteAttributeString("publicationdate", "2005-04-07");
    newRange->WriteAttributeString("ISBN", "0");
    newRange->WriteStartElement("title");
        newRange->WriteString("New Book");
    newRange->WriteEndElement();
    newRange->WriteStartElement("author");
        newRange->WriteStartElement("first-name");
            newRange->WriteString("First Name");
        newRange->WriteEndElement();
        newRange->WriteStartElement("last-name");
            newRange->WriteString("Last Name");
        newRange->WriteEndElement();
    newRange->WriteEndElement();
    newRange->WriteElementString("price", "$0.00");
newRange->WriteEndElement();
newRange->Close();
Console::WriteLine(navigator->OuterXml);
