XPathNavigator.Name Property

Definition

Namespace:

System.Xml.XPath

Assemblies:

netstandard.dll, System.Xml.ReaderWriter.dll

Source:

XPathNavigator.cs

When overridden in a derived class, gets the qualified name of the current node.

C#

public abstract string Name { get; }

Property Value

String

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

Examples

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

C#

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 (string.IsNullOrEmpty(navigator.Prefix))
                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.

Remarks

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

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

XPathNodeType	Property Value
Element	The qualified name of the Element. In the following example, <bk:book>, the name of the element node is bk:book.
Attribute	The qualified name of the Attribute. In the following example, <book bk:genre='novel'>, the name of the Attribute node is bk:genre.
Namespace	The prefix associated with the namespace URI. In the following namespace declaration, xmlns:bk='urn:samples', the Name property returns bk.
ProcessingInstruction	The target of the ProcessingInstruction. In the following example, <?xml-stylesheet type='text/xsl' href= 'books.xsl'?>, the Name property returns xml-stylesheet.
All other XPathNodeType nodes	String.Empty.
