Exemplos

O exemplo a seguir usa a CanEdit propriedade para exibir os CanEdit valores das classes e XmlDocument das XPathDocument classes.

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)

O exemplo usa o books.xml arquivo como uma entrada.
