Well id isn’t really the root node: Login is.
It should just be a case of specifying the attributes (not tags, btw) using XmlElement.SetAttribute. You haven’t specified how you’re creating the file though – whether you’re using XmlWriter, the DOM, or any other XML API.
If you could give an example of the code you’ve got which isn’t working, that would help a lot. In the meantime, here’s some code which creates the file you described:
using System;
using System.Xml;
class Test
{
static void Main()
{
XmlDocument doc = new XmlDocument();
XmlElement root = doc.CreateElement("Login");
XmlElement id = doc.CreateElement("id");
id.SetAttribute("userName", "Tushar");
id.SetAttribute("passWord", "Tushar");
XmlElement name = doc.CreateElement("Name");
name.InnerText = "Tushar";
XmlElement age = doc.CreateElement("Age");
age.InnerText = "24";
id.AppendChild(name);
id.AppendChild(age);
root.AppendChild(id);
doc.AppendChild(root);
doc.Save("test.xml");
}
}
