how can I change the name of XML node?
this is sample

<?xml version="1.0"?>
<adresboek>
<adres>
<naam>Mark van Renswoude</naam>
<straat>ddden 24</straat>
<plaats>Scddd</plaats>

I copy this sample with using Clone();
and how can I change node name overthere.

<?xml version="1.0"?>

You can't change the name of a node, rather you need to create a new
node with a different name.

XmlDocument xml = new XmlDocument();

xml.Load("c:\x.xml");

XmlNode rootTextNode = xml.SelectSingleNode("vvt/dd");

XmlNode root = xml.SelectSingleNode("vvt");

XmlNode cloneTextNode = rootTextNode.Clone();

cloneTextNode. <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<is it
possible to change name here?

root.AppendChild(cloneTextNode);

xml.Save("c:\\b.xml");

No, as said, you cannot simply chane the name, you need to create a new
element node with the desired name, here is an example:

using System.Xml;

public class Test20031016 {
public static void Main (string[] args) {
XmlDocument xmlDocument = new XmlDocument();
xmlDocument.Load(@"test20031011.xml");
System.Console.WriteLine(xmlDocument.OuterXml);
XmlElement element = (XmlElement)
xmlDocument.GetElementsByTagName("god")[0];
XmlElement newElement = copyElementToName(element, "super-god");
xmlDocument.DocumentElement.AppendChild(newElement);
System.Console.WriteLine(xmlDocument.OuterXml);
}

public static XmlElement copyElementToName (XmlElement element,
string tagName) {
XmlElement newElement = element.OwnerDocument.CreateElement(tagName);
for (int i = 0; i < element.Attributes.Count; i++) {
newElement.SetAttributeNode((XmlAttribute)
element.Attributes[i].CloneNode(true));
}
for (int i = 0; i < element.ChildNodes.Count; i++) {
newElement.AppendChild(element.ChildNodes[i].CloneNode(true));
}
return newElement;
}
}

That function copyElementToName allows you to do what you want, if the
document is originally

<?xml version="1.0" encoding="UTF-8"?>
<gods>
<god value="Supergod">
<name>Kibo</name>
<home>http://www.kibo.com/</home>
</god>
</gods>

then the program outputs

<?xml version="1.0" encoding="UTF-8"?><gods><god
value="Supergod"><name>Kibo</na
me><home>http://www.kibo.com/</home></god><super-god
value="Supergod"><name>Kibo
</name><home>http://www.kibo.com/</home></super-god></gods>

Hi Martin,

I've been working on something similar, but trying to generalize it as well.
The concept is a function that will take two parameters (XmlDocument
inboundDocument, string attributeName) and will go through the XML document
recursively renaming elements by the value of their name attribute (if it
exists).

Sample input:

<?xml version="1.0" encoding="UTF-8"?>
<root>
<element name="Supergod">
<element name="GodName">Kibo</element>
<element name="GodHome">http://www.kibo.com/</element>
</element>
</root>

Required output:

<?xml version="1.0" encoding="UTF-8"?>
<root>
<Supergod>
<GodName>Kibo</GodName>
<GodHome>http://www.kibo.com/</GodHome>
</Supergod>
</root>

I'm curious how you would approach this problem.
