Remarks

Note

In the .NET Framework 2.0, the recommended practice is to create XmlReader instances using the XmlReaderSettings class and the Create method. This allows you to take full advantage of all the new features introduced in the .NET Framework. For more information, see the Remarks section in the XmlReader reference page.

MoveToAttribute(String)

Moves to the attribute with the specified name.

public:
 override bool MoveToAttribute(System::String ^ name);
public override bool MoveToAttribute (string name);
override this.MoveToAttribute : string -> bool
Public Overrides Function MoveToAttribute (name As String) As Boolean

Parameters

name
String

The qualified name of the attribute.

Returns

true if the attribute is found; otherwise, false. If false, the reader's position does not change.

After calling this method, the Name, NamespaceURI, and Prefix properties reflect the properties of that attribute.

MoveToAttribute(String, String)

Moves to the attribute with the specified local name and namespace URI.

public:
 override bool MoveToAttribute(System::String ^ name, System::String ^ namespaceURI);
public override bool MoveToAttribute (string name, string namespaceURI);
override this.MoveToAttribute : string * string -> bool
Public Overrides Function MoveToAttribute (name As String, namespaceURI As String) As Boolean

Parameters

name
String

The local name of the attribute.

namespaceURI
String

The namespace URI of the attribute.

Returns

true if the attribute is found; otherwise, false. If false, the reader's position does not change.
