Example

Creating an XmlDocument, adding an XmlElement, and manipulating attributes.

// Using System.Xml;

XmlDocument doc = new XmlDocument();
XmlElement root = doc.CreateElement("books");
doc.AppendChild(root);

XmlElement book = doc.CreateElement("book");
book.SetAttribute("id", "b1");
book.SetAttribute("genre", "fantasy");

XmlElement title = doc.CreateElement("title");
title.InnerText = "The Hobbit";
book.AppendChild(title);

XmlElement author = doc.CreateElement("author");
author.InnerText = "J.R.R. Tolkien";
book.AppendChild(author);

root.AppendChild(book);

Console.WriteLine(doc.OuterXml);

Output:

<books>
  <book id="b1" genre="fantasy">
    <title>The Hobbit</title>
    <author>J.R.R. Tolkien</author>
  </book>
</books>
