プロパティ値

String

現在のノードのローカル名が含まれる String。現在のノードが名前を持たない場合 (たとえばテキスト ノードまたはコメント ノード) は Empty。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).

例

次の例では、ノードツリーを再帰的に反復処理し、ノードとノードに関する情報を表示し Element Text ます。The following example iterates over the node tree recursively, and displays information about Element and Text nodes.

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

static void RecursiveWalk(XPathNavigator^ navigator)

注釈

返されるローカル名は、 XPathNodeType 現在のノードのによって異なります。The local name returned depends on the XPathNodeType of the current node. たとえば、要素のローカル名 <bk:book> は book です。For example, the local name for the <bk:book> element is book.

次の表は、現在のノードのに基づいて、プロパティによって返される値を示して LocalName XPathNodeType います。The following table lists the value returned by the LocalName property, based on the XPathNodeType of the current node.

Xpath NodetypeXPathNodeType	プロパティ値Property Value
Element	要素のローカル名。The local name of the element.
Attribute	属性のローカル名。The local name of the attribute.
Namespace	名前空間 URI に関連付けられているプレフィックス。The prefix associated with the namespace URI.
ProcessingInstruction	処理命令の対象。The target of the processing instruction.
他のすべての XPathNodeType ノードAll other XPathNodeType nodes	String.Empty.String.Empty.
