名前空間: System.Xml
アセンブリ: System.Xml (system.xml.dll 内)
構文

Visual Basic (宣言)

Public Overridable ReadOnly
 Property OwnerElement As XmlElement

Visual Basic (使用法)

Dim value As XmlElement

value = instance.OwnerElement

C#

public virtual XmlElement OwnerElement { get;
 }

C++

public:
virtual property XmlElement^ OwnerElement {
    XmlElement^ get ();
}

J#

/** @property */
public XmlElement get_OwnerElement ()

JScript

public function get OwnerElement
 () : XmlElement

プロパティ値
属性が属している XmlElement。この属性が XmlElement の一部でない場合は null 参照 (Visual Basic では Nothing)。

使用例

属性を作成し、その属性の OwnerElement を表示する例を次に示します。

Visual Basic

Imports System
Imports System.IO
Imports System.Xml

public class Sample

  public shared sub Main()

    Dim doc as XmlDocument = new
 XmlDocument()
    doc.LoadXml("<book>" & _
                "<title>Pride And Prejudice</title>"
 & _
                "</book>") 

    'Create an attribute.
    Dim attr as XmlAttribute
    attr = doc.CreateAttribute("bk","genre"
,"urn:samples")
    attr.Value = "novel"

    'Try to display the attribute's owner element.
    if attr.OwnerElement is nothing
      Console.WriteLine("The attribute has not been added to an
 element")
      Console.WriteLine()
    else
      Console.WriteLine(attr.OwnerElement.OuterXml)
    end if

    'Add the attribute to an element.
    doc.DocumentElement.SetAttributeNode(attr)

    'Display the attribute's owner element.
    Console.WriteLine("Display the owner element...")
    Console.WriteLine(attr.OwnerElement.OuterXml)

  end sub
end class

    doc.DocumentElement.SetAttributeNode(attr);

    //Display the attribute's owner element.
    Console.WriteLine("Display the owner element...");
    Console.WriteLine(attr.OwnerElement.OuterXml);

   }
}

      Console::WriteLine( "The attribute has not been added to an element\r\n"
 );
   else
      Console::WriteLine( attr->OwnerElement->OuterXml );

   
   //Add the attribute to an element.
   doc->DocumentElement->SetAttributeNode( attr );
   
   //Display the attribute's owner element.
   Console::WriteLine( "Display the owner element..." );
   Console::WriteLine( attr->OwnerElement->OuterXml );
}

J#
