XContainer.ReplaceNodes Method (Object)

Replaces the children nodes of this document or element with the specified content.

Namespace:  System.Xml.Linq
Assemblies:   System.Xml.Linq (in System.Xml.Linq.dll)
  System.Xml.XDocument (in System.Xml.XDocument.dll)

'Declaration
Public Sub ReplaceNodes ( _
	content As Object _
)

Parameters

content
Type: System.Object

A content object containing simple content or a collection of content objects that replace the children nodes.

For details about the valid content that can be passed to this function, see Valid Content of XElement and XDocument Objects.

This method will raise the Changed and the Changing events.

This method has snapshot semantics. It first creates a copy of the new content. It then removes all children nodes of this node. Finally, it adds the new content as children nodes. This means that you can replace children nodes using a query on the children nodes themselves.

The following example creates an XML tree that contains children nodes. It then replaces all of the children nodes with a single element.

To see an example of replacing the children nodes with the results of a LINQ query, see ReplaceNodes.

Dim root As XElement = _ 
    <Root>
        <Child>1</Child>
        <Child>2</Child>
        <Child>3</Child>
        <Child>4</Child>
        <Child>5</Child>
    </Root>
root.ReplaceNodes( _
    From el In root.Elements _
    Where el.Value >= 3 _
    Select el)
Console.WriteLine(root)

This example produces the following output:

<Root>
  <Child>3</Child>
  <Child>4</Child>
  <Child>5</Child>
</Root>
