XPathNavigator.ReplaceRange(XPathNavigator) Méthode

Définition

Remplace une plage de nœuds frères allant du nœud actuel au nœud spécifié.

public:
 virtual System::Xml::XmlWriter ^ ReplaceRange(System::Xml::XPath::XPathNavigator ^ lastSiblingToReplace);
public virtual System.Xml.XmlWriter ReplaceRange (System.Xml.XPath.XPathNavigator lastSiblingToReplace);
abstract member ReplaceRange : System.Xml.XPath.XPathNavigator -> System.Xml.XmlWriter
override this.ReplaceRange : System.Xml.XPath.XPathNavigator -> System.Xml.XmlWriter
Public Overridable Function ReplaceRange (lastSiblingToReplace As XPathNavigator) As XmlWriter

Paramètres

lastSiblingToReplace
XPathNavigator

XPathNavigator positionné sur le dernier nœud frère de la plage à remplacer.

Retours

XmlWriter

Objet XmlWriter permettant de spécifier la plage de remplacement.

Exceptions

XPathNavigator spécifié est null.

Le XPathNavigator ne prend pas en charge la modification.

Le dernier nœud à remplacer spécifié n'est pas un nœud frère valide du nœud actuel.

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);
XmlDocument document = new XmlDocument();
document.Load("contosoBooks.xml");
XPathNavigator navigator = document.CreateNavigator();

XmlNamespaceManager manager = new 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);
Dim document As XmlDocument = New XmlDocument()
document.Load("contosoBooks.xml")
Dim navigator As XPathNavigator = document.CreateNavigator()

Dim manager As XmlNamespaceManager = New XmlNamespaceManager(document.NameTable)
manager.AddNamespace("bk", "http://www.contoso.com/books")

Dim first As XPathNavigator = navigator.SelectSingleNode("/bk:bookstore/bk:book[1]", manager)
Dim last As XPathNavigator = navigator.SelectSingleNode("/bk:bookstore/bk:book[2]", manager)

navigator.MoveTo(first)
Dim newRange As XmlWriter = 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)

L'exemple prend le fichier contosoBooks.xml comme entrée.

Remarques

La ReplaceRange méthode remplace une plage de nœuds frères du nœud actuel sur lequel le XPathNavigator nœud actuel est positionné sur (inclusif) vers le nœud spécifié par le XPathNavigator paramètre (inclusif).

Notes

La plage de remplacement n’est pas insérée tant que la Close méthode de l’objet XmlWriter n’est pas appelée.
