XmlWhitespace.NodeType プロパティ

2008-03-28

ノードの種類を取得します。

Overrides Public ReadOnly Property NodeType As XmlNodeType
[C#]
public override XmlNodeType NodeType {get;}
[C++]
public: __property XmlNodeType get_NodeType();
[JScript]
public override function get NodeType() : XmlNodeType;

プロパティ値

XmlWhitespace ノードの場合、値は XmlNodeType.Whitespace です。
