The WriteStartElement() method creates the root element, and sets the version attribute of this element to 2.0: XMLFeed.WriteStartDocument() XMLFeed.WriteStartElement(”rss”) XMLFeed.WriteAttributeString(”version”, “2.0″) Next, the code creates the element along with the

Each time the code finds a news item, it writes a starting element and adds the and <description> elements.
