Answer 1

Use ImportNode method:

var d1 = new XmlDocument();
d1.LoadXml("<Tags><Tag name =\"1\"></Tag></Tags>");

var d2 = new XmlDocument();
d2.LoadXml("<Tags><Tag name =\"2\"></Tag></Tags>");

var newNode = d1.ImportNode(d2.SelectSingleNode("/Tags/Tag"), true);
d1.DocumentElement.AppendChild(newNode);

Console.WriteLine(d1.OuterXml);

Answer 2

I suggest you to use LINQ to XML:

var firstDoc = XDocument.Load("file1.xml"); // load 1st file
var tagElement = XElement.Load("file2.xml"); // load <Tag> element from 2nd file
firstDoc.Root.Add(tagElement); // add <Tag> element to 1st file <Tags> element
firstDoc.Save("file1.xml"); // save 1st file
