XPathNodeIterator Class
Assembly: System.Xml (in system.xml.dll)
An XPathNodeIterator object returned by the XPathNavigator class is not positioned on the first node in a selected set of nodes. A call to the MoveNext method of the XPathNodeIterator class must be made to position the XPathNodeIterator object on the first node in the selected set of nodes.
Notes to Inheritors When you inherit from the XPathNodeIterator class, you must override the following members:-
MoveNext
The following example uses the Select method of the XPathNavigator class to select a node set using the XPathNodeIterator class.
Dim document As XPathDocument = New XPathDocument("books.xml") Dim navigator As XPathNavigator = document.CreateNavigator() Dim nodes As XPathNodeIterator = navigator.Select("/bookstore/book") Dim nodesNavigator As XPathNavigator = nodes.Current Dim nodesText As XPathNodeIterator = nodesNavigator.SelectDescendants(XPathNodeType.Text, False) While nodesText.MoveNext() Console.Write(nodesText.Current.Name) Console.WriteLine(nodesText.Current.Value) End While
The example takes the books.xml file as input.
