XmlAttributeCollection.InsertAfter(XmlAttribute, XmlAttribute) 方法

定义

命名空间:

System.Xml

程序集:

System.Xml.dll, System.Xml.XmlDocument.dll

程序集:

System.Xml.ReaderWriter.dll

程序集:

System.Xml.XmlDocument.dll

程序集:

System.Xml.dll

程序集:

将指定特性直接插入到指定引用特性之后。

public:
 System::Xml::XmlAttribute ^ InsertAfter(System::Xml::XmlAttribute ^ newNode, System::Xml::XmlAttribute ^ refNode);

public:
 virtual System::Xml::XmlAttribute ^ InsertAfter(System::Xml::XmlAttribute ^ newNode, System::Xml::XmlAttribute ^ refNode);

public System.Xml.XmlAttribute InsertAfter (System.Xml.XmlAttribute newNode, System.Xml.XmlAttribute refNode);

public System.Xml.XmlAttribute InsertAfter (System.Xml.XmlAttribute newNode, System.Xml.XmlAttribute? refNode);

public virtual System.Xml.XmlAttribute InsertAfter (System.Xml.XmlAttribute newNode, System.Xml.XmlAttribute refNode);

member this.InsertAfter : System.Xml.XmlAttribute * System.Xml.XmlAttribute -> System.Xml.XmlAttribute

abstract member InsertAfter : System.Xml.XmlAttribute * System.Xml.XmlAttribute -> System.Xml.XmlAttribute
override this.InsertAfter : System.Xml.XmlAttribute * System.Xml.XmlAttribute -> System.Xml.XmlAttribute

Public Function InsertAfter (newNode As XmlAttribute, refNode As XmlAttribute) As XmlAttribute

Public Overridable Function InsertAfter (newNode As XmlAttribute, refNode As XmlAttribute) As XmlAttribute

参数

newNode

XmlAttribute

要插入的属性。

refNode

XmlAttribute

引用属性。 newNode 放置在 refNode 之后。

返回

XmlAttribute

要插入到集合中的 XmlAttribute。

例外

ArgumentException

newNode 是从创建此集合的文档之外的另一个文档创建的。 或者，refNode 不是此集合的成员。

示例

以下示例向文档添加新属性。

#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->InsertAfter( 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.InsertAfter(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.InsertAfter(newAttr, attrColl.ItemOf(0))

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

  end sub
end class

注解

如果集合中已存在具有相同名称的属性，则会从集合中删除原始属性，并 newNode 插入到集合中。 null如果是refNode，newNode则插入到集合的开头。

此方法是文档对象模型的 Microsoft 扩展， (DOM) 。
