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