XmlNode.ReplaceChild Method

Replaces the child node oldChild with newChild node.

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

abstract ReplaceChild : 
        newChild:XmlNode * 
        oldChild:XmlNode -> XmlNode 
override ReplaceChild : 
        newChild:XmlNode * 
        oldChild:XmlNode -> XmlNode 

Parameters

newChild
Type: System.Xml.XmlNode
The new node to put in the child list.
oldChild
Type: System.Xml.XmlNode
The node being replaced in the list.

Return Value

Type: System.Xml.XmlNode
The node replaced.

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.

This node is read-only.

The oldChild is not a child of this node.

If the newChild is already in the tree, it is first removed.

If the newChild was created from another document, you can use XmlDocument.ImportNode to import the node to the current document. The imported node can then be passed to the ReplaceChild method.

Notes to Inheritors

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

The following example replaces the title element in the XML document.
