This class is an enumerated collection of nodes returned by XmlDocument.GetElementsByTagName( ). Nodes contained in the list can be retrieved by index or iterated through via the IEnumerator returned by GetEnumerator( ). Changes to the nodes in the list are immediately reflected in the XmlNodeList's properties and methods. For example, if you add a sibling to a node in the list, it appears in the list.
