下面的示例创建一个新的元素,并将其添加到文档中。The following example creates a new element and adds it to the document.

#using <System.Xml.dll>

using namespace System;
using namespace System::IO;
using namespace System::Xml;
int main()
{
   
   //Create the XmlDocument.
   XmlDocument^ doc = gcnew XmlDocument;
   doc->LoadXml( "<book genre='novel' ISBN='1-861001-57-5'><title>Pride And Prejudice</title></book>" );
   
   //Create a new node and add it to the document.
   //The text node is the content of the price element.
   XmlElement^ elem = doc->CreateElement( "price" );
   XmlText^ text = doc->CreateTextNode( "19.95" );
   doc->DocumentElement->AppendChild( elem );
   doc->DocumentElement->LastChild->AppendChild( text );
   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()
  {
    //Create the XmlDocument.
    XmlDocument doc = new XmlDocument();
    doc.LoadXml("<book genre='novel' ISBN='1-861001-57-5'>" +
                "<title>Pride And Prejudice</title>" +
                "</book>");

    //Create a new node and add it to the document.
    //The text node is the content of the price element.
    XmlElement elem = doc.CreateElement("price");
    XmlText text = doc.CreateTextNode("19.95");
    doc.DocumentElement.AppendChild(elem);
    doc.DocumentElement.LastChild.AppendChild(text);

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

        doc.LoadXml("<book genre='novel' ISBN='1-861001-57-5'>"  & _
                    "<title>Pride And Prejudice</title>"  & _

        'The text node is the content of the price element.
        Dim elem As XmlElement = doc.CreateElement("price")
        Dim text As XmlText = doc.CreateTextNode("19.95")
        doc.DocumentElement.AppendChild(elem)
        doc.DocumentElement.LastChild.AppendChild(text)
        
        Console.WriteLine("Display the modified XML...")
        doc.Save(Console.Out)
    End Sub
End Class

注解

尽管此方法会在文档的上下文中创建新的对象,但它不会自动将新对象添加到文档树。Although this method creates the new object in the context of the document, it does not automatically add the new object to the document tree. 若要添加新的对象,则必须显式调用某个节点插入方法。To add the new object, you must explicitly call one of the node insert methods.

根据 W3C可扩展标记语言(XML)1.0 建议,仅在元素、属性和 EntityReference 节点内允许文本节点。According to the W3C Extensible Markup Language (XML) 1.0 recommendation, Text nodes are only allowed within Element, Attribute and EntityReference nodes.
