Answer 1

Don't have VS here so can't confirm that this works but something like this:

XmlDocument xd = new XmlDocument();
xd.Load("oldxmlfile.xml");
XmlNode oldNode = xd["nameOfRootNode"];
xd.RemoveAll();
XmlNode newParent = xd.CreateNode("nodename");
newParent.AppendChild(oldNode);
xd.AppendChild(newParent);
xd.Save("newXmlFile.xml");

Answer 2

You can clone the old node, append the clone, and remove the original:

(edit; I forgot that AppendChild will move the node if it is already there... no need to clone and remove...)

XmlDocument doc = new XmlDocument();
// load the current xml
doc.LoadXml(xml);
// create a new "newnode" node and add it into the tree
XmlElement newnode = (XmlElement) doc.DocumentElement.AppendChild(doc.CreateElement("newnode"));
// locate the original "books" node and move it
newnode.AppendChild(doc.SelectSingleNode("/bookstore/books"));
// show the result
Console.WriteLine(doc.OuterXml);

Answer 3

Try this:-

XmlDocument doc = new XmlDocument();
doc.Load("BookStore.xml");
XmlElement newNode = doc.CreateElement("newnode");
doc.DocumentElement.AppendChild(newNode);
newNode.AppendChild(doc.SelectSingleNode("/bookstore/books"));
doc.Save("BookStore.xml");
