MoveToNextAttribute Method

XPathNavigator.MoveToNextAttribute Method

When overridden in a derived class, moves the XPathNavigator to the next attribute.

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

public abstract bool MoveToNextAttribute()

Return Value

Type: System.Boolean
Returns true if the XPathNavigator is successful moving to the next attribute; false if there are no more attributes. If false, the position of the XPathNavigator is unchanged.

If the XPathNavigator is not currently positioned on an attribute, this method returns false and the position of the XPathNavigator does not change.

When the XPathNavigator is positioned on an attribute, the methods MoveToNext, MoveToPrevious, and MoveToFirst methods are not applicable. These methods always return false and do not change the position of the XPathNavigator.

After the XPathNavigator is positioned on an attribute, you can call MoveToParent to move to the owner element.

The following example uses the MoveToFirstAttribute and MoveToNextAttribute methods to display all the attributes for each book in the books.xml file.


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

// Select all book nodes and display all attributes on each book.
XPathNodeIterator nodes = navigator.SelectDescendants("book", "", false);
while (nodes.MoveNext())
{
    XPathNavigator navigator2 = nodes.Current.Clone();
    navigator2.MoveToFirstAttribute();
    Console.WriteLine("{0} = {1}", navigator2.Name, navigator2.Value);

    while (navigator2.MoveToNextAttribute())
    {
        Console.WriteLine("{0} = {1}", navigator2.Name, navigator2.Value);
    }

    Console.WriteLine();
}


The example takes the books.xml file as an input.
