XmlNodeReader.NodeType プロパティ

現在の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

現在のノードの型を表す XmlNodeType 値の 1 つ。

この例では、入力として、 items.xml というファイルを使用しています。

<?xml version="1.0"?>
<!-- This is a sample XML document -->
<!DOCTYPE Items [<!ENTITY number "123">]>
<Items>
  <Item>Test with an entity: &number;</Item>
  <Item>test with a child element <more/> stuff</Item>
  <Item>test with a CDATA section <![CDATA[<456>]]> def</Item>
  <Item>Test with a char entity: &#65;</Item>
  <!-- Fourteen chars in this element.-->
  <Item>1234567890ABCD</Item>
</Items>
