Examples

The following example uses the InnerXml property to display the contents of the first book element in the contosoBooks.xml file and its child nodes in the XPathNavigator.

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

navigator->MoveToChild("bookstore", "http://www.contoso.com/books");
navigator->MoveToChild("book", "http://www.contoso.com/books");

Console::WriteLine(navigator->InnerXml);

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

navigator.MoveToChild("bookstore", "http://www.contoso.com/books");
navigator.MoveToChild("book", "http://www.contoso.com/books");

Console.WriteLine(navigator.InnerXml);

Dim document As XPathDocument = New XPathDocument("contosoBooks.xml")
Dim navigator As XPathNavigator = document.CreateNavigator()

navigator.MoveToChild("bookstore", "http://www.contoso.com/books")
navigator.MoveToChild("book", "http://www.contoso.com/books")

Console.WriteLine(navigator.InnerXml)

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

Remarks

Note

The InnerXml and OuterXml properties are not very efficient. If performance is a priority, it is more efficient to use the node navigation methods of the XPathNavigator to get values of child nodes.
