I hope this will work.

XmlDocument xmlDocument = new XmlDocument();
 xmlDocument.PreserveWhitespace = false;
 xmlDocument.Load(@"file.xml");
 
XmlNode fieldNode = xmlDocument.SelectSingleNode(
 @"/root/field[@name = '3']");
 
if (fieldNode != null) {
 fieldNode.ParentNode.InsertBefore(fieldNode,
 fieldNode.PreviousSibling);
 }
 
// save changes somewhere
 // in this example simply the console to show changes
 xmlDocument.Save(Console.Out);

Solution 2

Come on, you don't need it anyway: "1", "2" and "3" are invalid tag names, so this is not even a well-formed XML, won't parse.
