XmlAttributeCollection.Append(XmlAttribute) 方法

定义

将指定属性作为集合中的最后一个节点插入。

public:
 System::Xml::XmlAttribute ^ Append(System::Xml::XmlAttribute ^ node);
public:
 virtual System::Xml::XmlAttribute ^ Append(System::Xml::XmlAttribute ^ node);
public System.Xml.XmlAttribute Append(System.Xml.XmlAttribute node);
public virtual System.Xml.XmlAttribute Append(System.Xml.XmlAttribute node);
member this.Append : System.Xml.XmlAttribute -> System.Xml.XmlAttribute
abstract member Append : System.Xml.XmlAttribute -> System.Xml.XmlAttribute
override this.Append : System.Xml.XmlAttribute -> System.Xml.XmlAttribute
Public Function Append (node As XmlAttribute) As XmlAttribute
Public Overridable Function Append (node As XmlAttribute) As XmlAttribute

参数

node
XmlAttribute

要插入的属性。

返回

XmlAttribute 追加到集合中。

例外

node 是从与创建此集合的文档不同的文档创建的。

示例

以下示例向文档添加新属性。

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.Append(newAttr);

    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.Append(newAttr)

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

  end sub
end class

注解

如果集合中已存在同名的属性,则会从集合中删除原始属性,并将其 node 添加到集合末尾。

此方法是文档对象模型(DOM)的Microsoft扩展。
