Selects all the descendant nodes of the current node with the local name and namespace URI specified.
An System.Xml.XPath.XPathNodeIterator that contains the selected nodes.
If string.Empty is specified as the name parameter, all descendant nodes that belong to the specified namespace URI are selected. If string.Empty is specified as the namespaceURI parameter, all descendant nodes with the specified local name that belong to no namespace are selected. If both the local name and namespace URI parameters are string.Empty, all descendant nodes that belong to no namespace are selected.
A descendant is a child or a child of a child and so on; thus the selected nodes will never contain attribute or namespace nodes.
The XPathNavigator.SelectDescendants(string, string, bool) method has no effect on the state of the System.Xml.XPath.XPathNavigator.
