XPathNavigator.CanEdit Property

 

Gets a value indicating whether the XPathNavigator can edit the underlying XML data.

Namespace:   System.Xml.XPath
Assembly:  System.Xml (in System.Xml.dll)

public virtual bool CanEdit { get; }

Property Value

Type: System.Boolean

true if the XPathNavigator can edit the underlying XML data; otherwise false.

The CanEdit property has different values based on the three different implementations of the IXPathNavigable interface in the .NET Framework. The CanEdit values for XPathNavigator objects created by each implementation are listed in the following table.

IXPathNavigable Implementation

CanEdit Value

XPathDocument

false

XmlDocument

true

The following example uses the CanEdit property to display the CanEdit values of the XPathDocument and XmlDocument 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);

The example takes the books.xml file as an input.
