XmlNode.InsertAfter Method

Inserts the specified node immediately after the specified reference node.

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

'Declaration
Public Overridable Function InsertAfter ( _
	newChild As XmlNode, _
	refChild As XmlNode _
) As XmlNode

Parameters

newChild
Type: System.Xml.XmlNode

The XmlNode to insert.

refChild
Type: System.Xml.XmlNode

The XmlNode that is the reference node. The newNode is placed after the refNode.

Return Value

Type: System.Xml.XmlNode
The node being inserted.

ExceptionCondition
InvalidOperationException

This node is of a type that does not allow child nodes of the type of the newChild node.

The newChild is an ancestor of this node.

ArgumentException

The newChild was created from a different document than the one that created this node.

The refChild is not a child of this node.

This node is read-only.

If refChild is Nothing, insert newChild at the beginning of the list of child nodes. All the contents of the newChild are inserted, in the same order, after refChild. If the newChild is already in the tree, it is removed from its original position and added to its target position. For more information about inserting nodes, see Inserting Nodes into an XML Document.

If the node being inserted was created from another document, you can use XmlDocument.ImportNode to import the node to the current document. The imported node can then be inserted into the current document.

This method is a Microsoft extension to the Document Object Model (DOM).

Notes to Inheritors

When overriding InsertAfter in a derived class, in order for events to be raised correctly, you must call the InsertAfter method of the base class.

The following example adds a new node to the XML document.
