XPathNavigator.InsertAfter Method (String)

Creates a new sibling node after the currently selected node using the XML string specified.

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

public virtual void InsertAfter(
	string newSibling
)

Parameters

newSibling
Type: System.String
The XML data string for the new sibling node.

ExceptionCondition
ArgumentNullException

The XML string 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.

XmlException

The XML string parameter is not well-formed.

To create a new element node, include all XML syntax in the XML string parameter. The string for a new book node is InsertAfter("<book/>"). The string for inserting the text "book" after the current node's text node is InsertAfter("book"). If the XML string contains multiple nodes, all nodes are added.

The following are important notes to consider when using the InsertAfter method.

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.


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");

navigator.InsertAfter("<pages>100</pages>");

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


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