<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<root>
  <level>
    <node1 />
    <node2 />
    <node3 />

给你:

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
}
