XElement.ReplaceAll Method (Object[])

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)

public void ReplaceAll(
	params Object[] content
)

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 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.

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

XElement xmlTree1 = new XElement("Root",
    new XElement("Child1", 1),
    new XElement("Child2", 2),
    new XElement("Child3", 3),
    new XElement("Child4", 4),
    new XElement("Child5", 5),
    new XElement("Child6", 6)
);

XElement root = new XElement("Root",
    new XElement("Child", "child content")
);

root.ReplaceAll(
    from el in xmlTree1.Elements()
    where((int)el >= 3 && (int)el <= 5)
    select el
);
Console.WriteLine(root);

This example produces the following output:

<Root>
  <Child3>3</Child3>
  <Child4>4</Child4>
  <Child5>5</Child5>
</Root>
