 virtual void InsertAfter(System::Xml::XPath::XPathNavigator ^ newSibling);

public virtual void InsertAfter (System.Xml.XPath.XPathNavigator newSibling);

abstract member InsertAfter : System.Xml.XPath.XPathNavigator -> unit
override this.InsertAfter : System.Xml.XPath.XPathNavigator -> unit

Public Overridable Sub InsertAfter (newSibling As XPathNavigator)

Parameters

newSibling: XPathNavigator

An XPathNavigator object positioned on the node to add as the new sibling node.

Exceptions

ArgumentNullException

The XPathNavigator object parameter is null.

InvalidOperationException

The position of the XPathNavigator does not allow a new sibling node to be inserted after the current node.

NotSupportedException

The XPathNavigator does not support editing.

Examples

In the following example a new pages element is inserted after the price child element of the first book element in the contosoBooks.xml file using the node contained in the XPathNavigator object specified. The http://www.contoso.com/books namespace is specified so that the new sibling element is inserted using the same namespace as the XML document.

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

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

XmlDocument^ childNodes = gcnew XmlDocument();
childNodes->Load(gcnew StringReader("<pages xmlns=\"http://www.contoso.com/books\">100</pages>"));
XPathNavigator^ childNodesNavigator = childNodes->CreateNavigator();

navigator->InsertAfter(childNodesNavigator);

navigator->MoveToParent();
Console::WriteLine(navigator->OuterXml);

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

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

XmlDocument childNodes = new XmlDocument();
childNodes.Load(new StringReader("<pages xmlns=\"http://www.contoso.com/books\">100</pages>"));
XPathNavigator childNodesNavigator = childNodes.CreateNavigator();

navigator.InsertAfter(childNodesNavigator);

navigator.MoveToParent();
Console.WriteLine(navigator.OuterXml);

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

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

Dim childNodes As XmlDocument = New XmlDocument()
childNodes.Load(New StringReader("<pages xmlns='http://www.contoso.com/books'>100</pages>"))
Dim childNodesNavigator As XPathNavigator = childNodes.CreateNavigator()

navigator.InsertAfter(childNodesNavigator)

navigator.MoveToParent()
Console.WriteLine(navigator.OuterXml)
