定義

指定した属性を、指定した参照属性の直前に挿入します。Inserts the specified attribute immediately before the specified reference attribute.

public:
 System::Xml::XmlAttribute ^ InsertBefore(System::Xml::XmlAttribute ^ newNode, System::Xml::XmlAttribute ^ refNode);
public:
 virtual System::Xml::XmlAttribute ^ InsertBefore(System::Xml::XmlAttribute ^ newNode, System::Xml::XmlAttribute ^ refNode);
public System.Xml.XmlAttribute InsertBefore (System.Xml.XmlAttribute newNode, System.Xml.XmlAttribute refNode);
public virtual System.Xml.XmlAttribute InsertBefore (System.Xml.XmlAttribute newNode, System.Xml.XmlAttribute refNode);
member this.InsertBefore : System.Xml.XmlAttribute * System.Xml.XmlAttribute -> System.Xml.XmlAttribute
abstract member InsertBefore : System.Xml.XmlAttribute * System.Xml.XmlAttribute -> System.Xml.XmlAttribute
override this.InsertBefore : System.Xml.XmlAttribute * System.Xml.XmlAttribute -> System.Xml.XmlAttribute
Public Function InsertBefore (newNode As XmlAttribute, refNode As XmlAttribute) As XmlAttribute
Public Overridable Function InsertBefore (newNode As XmlAttribute, refNode As XmlAttribute) As XmlAttribute

パラメーター

newNode
XmlAttribute

挿入する属性。The attribute to insert.

refNode
XmlAttribute

参照属性。The reference attribute. newNoderefNode の前に配置されます。newNode is placed before the refNode.

戻り値

コレクションに挿入する XmlAttributeThe XmlAttribute to insert into the collection.

例外

このコレクションを作成したドキュメントと異なるドキュメントから newNode が作成されました。The newNode was created from a document different from the one that created this collection. または、refNode がこのコレクションのメンバーではありません。Or the refNode is not a member of this collection.

次の例では、ドキュメントに新しい属性を追加します。The following example adds a new attribute to a document.

#using <System.Xml.dll>

using namespace System;
using namespace System::IO;
using namespace System::Xml;

int main()
{
   XmlDocument^ doc = gcnew XmlDocument;
   doc->LoadXml( "<book ISBN='1-861001-57-5'><title>Pride And Prejudice</title></book>" );
   
   //Create a new attribute.
   XmlAttribute^ newAttr = doc->CreateAttribute( "genre" );
   newAttr->Value = "novel";
   
   //Create an attribute collection and add the new attribute
   //to the collection.
   XmlAttributeCollection^ attrColl = doc->DocumentElement->Attributes;
   attrColl->InsertBefore( newAttr, attrColl[ 0 ] );
   Console::WriteLine( "Display the modified XML...\r\n" );
   Console::WriteLine( doc->OuterXml );
}
using System;
using System.IO;
using System.Xml;

public class Sample
{
  public static void Main(){
  
    XmlDocument doc = new XmlDocument();
    doc.LoadXml("<book ISBN='1-861001-57-5'>" +
                "<title>Pride And Prejudice</title>" +
                "</book>");      

    //Create a new attribute.
    XmlAttribute newAttr = doc.CreateAttribute("genre");
    newAttr.Value = "novel";

    //Create an attribute collection and add the new attribute
    //to the collection.
    XmlAttributeCollection attrColl = doc.DocumentElement.Attributes;
    attrColl.InsertBefore(newAttr, attrColl[0]);

    Console.WriteLine("Display the modified XML...\r\n");
    Console.WriteLine(doc.OuterXml);  
  }
}
Imports System.IO
Imports System.Xml

public class Sample

  public shared sub Main()
  
    Dim doc as XmlDocument = new XmlDocument()
    doc.LoadXml("<book ISBN='1-861001-57-5'>" & _
                "<title>Pride And Prejudice</title>" & _
                "</book>")      

    'Create a new attribute.
    Dim newAttr as XmlAttribute = doc.CreateAttribute("genre")
    newAttr.Value = "novel"

    'Create an attribute collection and add the new attribute
    'to the collection.  
    Dim attrColl as XmlAttributeCollection = doc.DocumentElement.Attributes
    attrColl.InsertBefore(newAttr, attrColl.ItemOf(0))

    Console.WriteLine("Display the modified XML...")
    Console.WriteLine(doc.OuterXml)

  end sub
end class

注釈

同じ名前の属性がコレクション内に既に存在する場合、元の属性がコレクションから削除され、コレクションに newNode が挿入されます。If an attribute with the same name is already present in the collection, the original attribute is removed from the collection and newNode is inserted into the collection. refNodenull場合は、newNode がコレクションの末尾に挿入されます。If refNode is null, newNode is inserted at the end of the collection.

このメソッドは、ドキュメントオブジェクトモデル (DOM) の Microsoft 拡張機能です。This method is a Microsoft extension to the Document Object Model (DOM).
