//Here is the variable with which you assign a new value to the attribute
string newValue = string.Empty
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(xmlFile);
XmlNode node = xmlDoc.SelectSingleNode("Root/Node/Element");
node.Attributes[0].Value = newValue;
xmlDoc.Save(xmlFile);

Here you go:
干得好：
XmlDocument xmldoc = new XmlDocument();
xmldoc.LoadXml(@"
<root>
<level>
<node1 />
<node2 />
<node3 />
</level>
</root>");
XmlElement node1 = xmldoc.SelectSingleNode("/root/level/node1") as XmlElement;
if (node1 != null)
{
node1.InnerText = "something"; // if you want a text
node1.SetAttribute("attr", "value"); // if you want an attribute
node1.AppendChild(xmldoc.CreateElement("subnode1")); // if you want a subnode
}

XElement t = XElement.Load("filePath");
t.Element("level").Element("node1").Value = "";
t.Element("level").Element("node2").Value = "";
t.Element("level").Element("node3").Value = "";
t.Save("filePath");
