Replaces the child nodes and the attributes of this element with the specified content.

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

'Declaration
Public Sub ReplaceAll ( _
	ParamArray content As Object() _
)

Parameters

content
Type: System.Object ()
A parameter list of content objects.

This method first removes existing content and attributes. It then adds the specified content.

This method uses snapshot semantics—that is, it creates a separate copy of the new content before replacing the contents of the current element with the new content. This means that you can query the contents of the current element and use the results of the query as the specified new content.

For more information about the valid content that can be passed to this function, see Valid Content of XElement and XDocument Objects in the .NET Framework documentation.

This method will raise the Changed and the Changing events.

The following example passes the results of a LINQ query to this method, replacing the contents of an element with the query results.


Dim output As New StringBuilder
Dim xmlTree1 As XElement = _
        <Root>
            <Child1>1</Child1>
            <Child2>2</Child2>
            <Child3>3</Child3>
            <Child4>4</Child4>
            <Child5>5</Child5>
            <Child6>6</Child6>
        </Root>

Dim root As XElement = <Root>
                           <Child>child content</Child>
                       </Root>

root.ReplaceAll( _
    From el In xmlTree1.Elements() _
    Where el.Value >= 3 And el.Value <= 5 _
    Select el _
)

output.Append(root)
output.Append(Environment.NewLine)


OutputTextBlock.Text = output.ToString()
