XPathNavigator.LocalName Property

public:
 abstract property System::String ^ LocalName { System::String ^ get(); };

public abstract string LocalName { get; }

member this.LocalName : string

Public MustOverride ReadOnly Property LocalName As String

Property Value

A String that contains the local 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.

Remarks

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.
