how to delete where id = test?

Answer 1

You could try this:

XmlDocument d = new XmlDocument();
d.Load("MyFileName.Xml");

XmlNode t = d.SelectSingleNode("/path/to/node[@id='test']");
t.ParentNode.RemoveChild(t);

d.Save();

Answer 2

Using XmlDocument as an example, and treating id as an attribute:

XmlDocument doc = new XmlDocument();
doc.LoadXml(@"<xml>
  <row id='123'/>
  <row id='456'/>
  <row id='789'/>
</xml>");
XmlNode node = doc.SelectSingleNode("//row[@id=456]");
node.ParentNode.RemoveChild(node);
string s = doc.OuterXml;
