How do you Modify a node name?

How do you Modify a node name?

  The name property on the node is readonly, so I think you'd have to append all the child nodes into your new node, then replace the existing one.
  
  Example:
  

  // Replacing <user2> with <user1> XmlDocument doc = new XmlDocument(); ... XmlNode user2Node = doc.SelectSingleNode("user2"); XmlNode user1Node = doc.CreateElement("user1"); foreach(XmlNode childNode in user2Node.ChildNodes) {    user1Node.AppendChild(childNode); } // if you have attributes, you'll need this loop too foreach(XmlAttribute attribute in user2Node.Attributes) {    // you have to clone the attribute, it seems to mess with user2Node.Attributes collection    user1Node.Attributes.Append((XmlAttribute)attribute.Clone()); } doc.ReplaceChild(user1Node, user2Node);

  If you care about how it handles namespaces, then you might want to use this version which allows you to actually change the namespace of an element, as well as it's name.
  
  

  void RenameNode(XmlNode node, string prefix, string name, string nsuri) {
      XmlDocument doc = node.OwnerDocument;
      XmlNode newNode = doc.CreateElement(prefix, name, nsuri);
      XmlAttributeCollection attributes = node.Attributes;
      XmlAttributeCollection newAttributes = newNode.Attributes;
      while (attributes.Count > 0) {
          XmlAttribute a = attributes[0];
          if (a.LocalName == "xmlns" && a.Value == node.NamespaceURI) {
              // Strip out any namespace declarations that no longer apply.
              attributes.RemoveAt(0);
          } else {
              newAttributes.Append(a);
          } 
      }
      while (node.HasChildNodes){
          newNode.AppendChild(node.FirstChild);
      }
      node.ParentNode.ReplaceChild(newNode, node);
  }

  Thats excelent.  I thought so. 
  
  Thanks for the code.  Very efficient, I did pretty much the same but with little elegance. 
  
  Many thanks
