XNode.ReplaceWith Method

Definition

Namespace:

System.Xml.Linq

Assembly:

System.Xml.XDocument.dll

Replaces this node with the specified content.

Overloads

ReplaceWith(Object)	Replaces this node with the specified content.
ReplaceWith(Object[])	Replaces this node with the specified content.

Examples

The following example uses this method to replace the contents of a node with different content.

XElement xmlTree = new XElement("Root",  
    new XElement("Child1", "child1 content"),  
    new XElement("Child2", "child2 content"),  
    new XElement("Child3", "child3 content"),  
    new XElement("Child4", "child4 content"),  
    new XElement("Child5", "child5 content")  
);  
XElement child3 = xmlTree.Element("Child3");  
child3.ReplaceWith(  
    new XElement("NewChild", "new content")  
);  
Console.WriteLine(xmlTree);  

Dim xmlTree As XElement = _   
        <Root>  
            <Child1>child1 content</Child1>  
            <Child2>child2 content</Child2>  
            <Child3>child3 content</Child3>  
            <Child4>child4 content</Child4>  
            <Child5>child5 content</Child5>  
        </Root>  

Dim child3 As XElement = xmlTree.<Child3>(0)  
child3.ReplaceWith(<NewChild>new content</NewChild>)  
Console.WriteLine(xmlTree)  

This example produces the following output:

<Root>  
  <Child1>child1 content</Child1>  
  <Child2>child2 content</Child2>  
  <NewChild>new content</NewChild>  
  <Child4>child4 content</Child4>  
  <Child5>child5 content</Child5>  
</Root>  

Remarks

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

This method will raise the Changed and the Changing events.

The XContainer stores its child nodes as a singly-linked list of XNode objects. This means that the ReplaceWith method must traverse the list of direct child nodes under the parent container. Therefore, using this method might affect your performance.

ReplaceWith(Object)

Source:

XNode.cs

Replaces this node with the specified content.

public:
 void ReplaceWith(System::Object ^ content);

public void ReplaceWith (object? content);

member this.ReplaceWith : obj -> unit

Public Sub ReplaceWith (content As Object)

Parameters

content

Object

Content that replaces this node.

Examples

The following example uses this method to replace the contents of a node with different content.

XElement xmlTree = new XElement("Root",  
    new XElement("Child1", "child1 content"),  
    new XElement("Child2", "child2 content"),  
    new XElement("Child3", "child3 content"),  
    new XElement("Child4", "child4 content"),  
    new XElement("Child5", "child5 content")  
);  
XElement child3 = xmlTree.Element("Child3");  
child3.ReplaceWith(  
    new XElement("NewChild", "new content")  
);  
Console.WriteLine(xmlTree);  

Dim xmlTree As XElement = _   
        <Root>  
            <Child1>child1 content</Child1>  
            <Child2>child2 content</Child2>  
            <Child3>child3 content</Child3>  
            <Child4>child4 content</Child4>  
            <Child5>child5 content</Child5>  
        </Root>  

Dim child3 As XElement = xmlTree.<Child3>(0)  
child3.ReplaceWith(<NewChild>new content</NewChild>)  
Console.WriteLine(xmlTree)  

This example produces the following output:

<Root>  
  <Child1>child1 content</Child1>  
  <Child2>child2 content</Child2>  
  <NewChild>new content</NewChild>  
  <Child4>child4 content</Child4>  
  <Child5>child5 content</Child5>  
</Root>  

Remarks

This method first removes this node from its parent, and then adds the specified content to this node's parent, in the place of this node.

The XContainer stores its child nodes as a singly-linked list of XNode objects. This means that the ReplaceWith method must traverse the list of direct child nodes under the parent container. Therefore, using this method might affect your performance.

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

This method will raise the Changed and the Changing events.

Examples

The following example shows using the results of a LINQ to XML query as the input to this method.

XElement srcTree = new XElement("Root",  
    new XElement("Element1", 1),  
    new XElement("Element2", 2),  
    new XElement("Element3", 3),  
    new XElement("Element4", 4),  
    new XElement("Element5", 5)  
);  
XElement xmlTree = new XElement("Root",  
    new XElement("Child1", 1),  
    new XElement("Child2", 2),  
    new XElement("Child3", 3),  
    new XElement("Child4", 4),  
    new XElement("Child5", 5)  
);  
XElement child3 = xmlTree.Element("Child3");  
child3.ReplaceWith(  
    from el in srcTree.Elements()  
    where (int)el > 3  
    select el  
);  
Console.WriteLine(xmlTree);  

Dim srcTree As XElement = _   
        <Root>  
            <Element1>1</Element1>  
            <Element2>2</Element2>  
            <Element3>3</Element3>  
            <Element4>4</Element4>  
            <Element5>5</Element5>  
        </Root>  

Dim xmlTree As XElement = _   
        <Root>  
            <Child1>1</Child1>  
            <Child2>2</Child2>  
            <Child3>3</Child3>  
            <Child4>4</Child4>  
            <Child5>5</Child5>  
        </Root>  

Dim child3 As XElement = xmlTree.<Child3>(0)  
child3.ReplaceWith( _  
    From el In srcTree.Elements() _  
    Where (CInt(el) > 3) _  
    Select el)  

Console.WriteLine(xmlTree)  

This example produces the following output:

<Root>  
  <Child1>1</Child1>  
  <Child2>2</Child2>  
  <Element4>4</Element4>  
  <Element5>5</Element5>  
  <Child4>4</Child4>  
  <Child5>5</Child5>  
</Root>
