Remarks
Note
To take advantage of newer features, the recommended practice is to create XmlReader instances using the XmlReaderSettings class and the Create method. For more information, see the Remarks section in the XmlReader reference page.
This property is relevant to Element
, DocumentType
and XmlDeclaration
nodes only. (Other node types do not have attributes.)
