XmlNode.Attributes 属性

定义

获取一个 XmlAttributeCollection,它包含该节点的特性。Gets an XmlAttributeCollection containing the attributes of this node.

public:
 virtual property System::Xml::XmlAttributeCollection ^ Attributes { System::Xml::XmlAttributeCollection ^ get(); };
public virtual System.Xml.XmlAttributeCollection Attributes { get; }
member this.Attributes : System.Xml.XmlAttributeCollection
Public Overridable ReadOnly Property Attributes As XmlAttributeCollection

属性值

一个 XmlAttributeCollection,它包含该节点的特性。An XmlAttributeCollection containing the attributes of the node.

如果节点为 XmlNodeType.Element 类型,则返回该节点的属性。If the node is of type XmlNodeType.Element, the attributes of the node are returned. 对于其他类型的单元格,此属性返回 nullOtherwise, this property returns null.

示例

下面的示例将新特性添加到 XML 文档中。The following example adds a new attribute to the XML 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 xmlns:bk='urn:samples' bk:ISBN='1-861001-57-5'>"
   "<title>Pride And Prejudice</title>"
   "</book>" );
   XmlNode^ root = doc->FirstChild;
   
   //Create a new attribute.
   String^ ns = root->GetNamespaceOfPrefix( "bk" );
   XmlNode^ attr = doc->CreateNode( XmlNodeType::Attribute, "genre", ns );
   attr->Value = "novel";
   
   //Add the attribute to the document.
   root->Attributes->SetNamedItem( attr );
   Console::WriteLine( "Display the modified XML..." );
   doc->Save( Console::Out );
}

using System;
using System.IO;
using System.Xml;

public class Sample {

  public static void Main() {

    XmlDocument doc = new XmlDocument();
    doc.LoadXml("<book xmlns:bk='urn:samples' bk:ISBN='1-861001-57-5'>" +
                "<title>Pride And Prejudice</title>" +
                "</book>");

    XmlNode root = doc.FirstChild;

    //Create a new attribute.
    string ns = root.GetNamespaceOfPrefix("bk");
    XmlNode attr = doc.CreateNode(XmlNodeType.Attribute, "genre", ns);
    attr.Value = "novel";

    //Add the attribute to the document.
    root.Attributes.SetNamedItem(attr);

    Console.WriteLine("Display the modified XML...");
    doc.Save(Console.Out);
  }
}

        root.Attributes.SetNamedItem(attr)
        
        Console.WriteLine("Display the modified XML...")
        doc.Save(Console.Out)
