XPathDocument^ readOnlyDocument = gcnew XPathDocument("books.xml");
XPathNavigator^ readOnlyNavigator = readOnlyDocument->CreateNavigator();

XmlDocument^ editableDocument = gcnew XmlDocument();
editableDocument->Load("books.xml");
XPathNavigator^ editableNavigator = editableDocument->CreateNavigator();

Console::WriteLine("XPathNavigator.CanEdit from XPathDocument: {0}", readOnlyNavigator->CanEdit);
Console::WriteLine("XPathNavigator.CanEdit from XmlDocument: {0}", editableNavigator->CanEdit);
XPathDocument readOnlyDocument = new XPathDocument("books.xml");
XPathNavigator readOnlyNavigator = readOnlyDocument.CreateNavigator();

XmlDocument editableDocument = new XmlDocument();
editableDocument.Load("books.xml");
XPathNavigator editableNavigator = editableDocument.CreateNavigator();

Console.WriteLine("XPathNavigator.CanEdit from XPathDocument: {0}", readOnlyNavigator.CanEdit);
Console.WriteLine("XPathNavigator.CanEdit from XmlDocument: {0}", editableNavigator.CanEdit);
Dim readOnlyDocument As XPathDocument = New XPathDocument("books.xml")
Dim readOnlyNavigator As XPathNavigator = readOnlyDocument.CreateNavigator()

Dim editableDocument As XmlDocument = New XmlDocument()
editableDocument.Load("books.xml")
Dim editableNavigator As XPathNavigator = editableDocument.CreateNavigator()

Console.WriteLine("XPathNavigator.CanEdit from XPathDocument: {0}", readOnlyNavigator.CanEdit)
Console.WriteLine("XPathNavigator.CanEdit from XmlDocument: {0}", editableNavigator.CanEdit)

In diesem Beispiel wird die Datei books.xml als Eingabe verwendet.The example takes the books.xml file as an input.
