XPathNavigator.LocalName Property

When overridden in a derived class, gets the Name of the current node without any namespace prefix.

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

public abstract string LocalName { get; }
/** @property */
public abstract String get_LocalName ()

public abstract function get LocalName () : String

Property Value

A String that contains the local name of the current node, or String.Empty if the current node does not have a name (for example, text or comment nodes).

The local name returned depends on the XPathNodeType of the current node. For example, the local name for the <bk:book> element is book.

The following table lists the value returned by the LocalName property, based on the XPathNodeType of the current node.

XPathNodeType

Property Value

Element

The local name of the element.

Attribute

The local name of the attribute.

Namespace

The prefix associated with the namespace URI.

ProcessingInstruction

The target of the processing instruction.

All other XPathNodeType nodes

String.Empty.

The following example iterates over the node tree recursively, and displays information about Element and Text nodes.

static void XPathNavigatorMethods_MoveToNext()
{
    
    XPathDocument document = new XPathDocument("books.xml");
    XPathNavigator navigator = document.CreateNavigator();
    XPathNodeIterator nodeset = navigator.Select("descendant::book[author/last-name='Melville']");

    while (nodeset.MoveNext())
    {
        // Clone iterator here when working with it.
        RecursiveWalk(nodeset.Current.Clone());
    }
}

public static void RecursiveWalk(XPathNavigator navigator)
{
    switch (navigator.NodeType)
    {
        case XPathNodeType.Element:
            if (navigator.Prefix == String.Empty)
                Console.WriteLine("<{0}>", navigator.LocalName);
            else
                Console.Write("<{0}:{1}>", navigator.Prefix, navigator.LocalName);
                Console.WriteLine("\t" + navigator.NamespaceURI);
            break;
        case XPathNodeType.Text:
            Console.WriteLine("\t" + navigator.Value);
            break;
    }

    if (navigator.MoveToFirstChild())
    {
        do
        {
            RecursiveWalk(navigator);
        } while (navigator.MoveToNext());

        navigator.MoveToParent();
        if (navigator.NodeType == XPathNodeType.Element)
            Console.WriteLine("</{0}>", navigator.Name);
    }
    else
    {
        if (navigator.NodeType == XPathNodeType.Element)
        {
            Console.WriteLine("</{0}>", navigator.Name);
       }
    }
}

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