XPathNodeIterator.MoveNext Method

When overridden in a derived class, moves the XPathNavigator object returned by the Current property to the next node in the selected node set.

Namespace: System.Xml.XPath
Assembly: System.Xml (in system.xml.dll)

public abstract bool MoveNext ()
public abstract boolean MoveNext ()
public abstract function MoveNext () : boolean
Not applicable.

Return Value

true if the XPathNavigator object moved to the next node; false if there are no more selected nodes.

The XPathNodeIterator object is positioned on the first node in the selected node set only after the initial call to the MoveNext method. The node set is created in document order. Therefore, calling the MoveNext method moves to the next node in document order.

The following example uses the Select method of the XPathNavigator class to select a node set using the XPathNodeIterator class.

XPathDocument document = new XPathDocument("books.xml");
XPathNavigator navigator = document.CreateNavigator();

XPathNodeIterator nodes = navigator.Select("/bookstore/book");
XPathNavigator nodesNavigator = nodes.Current;

XPathNodeIterator nodesText = nodesNavigator.SelectDescendants(XPathNodeType.Text, false);

while (nodesText.MoveNext())
{
    Console.Write(nodesText.Current.Name);
    Console.WriteLine(nodesText.Current.Value);
}

The example takes the books.xml file as input.
