範例

下列範例會將大量的空格元新增至檔。

#using <System.Xml.dll>

using namespace System;
using namespace System::Xml;
int main()
{
   XmlDocument^ doc = gcnew XmlDocument;
   doc->LoadXml( "<author xml:space='preserve'><first-name>Eva</first-name><last-name>Corets</last-name></author>" );
   Console::WriteLine( "InnerText before..." );
   Console::WriteLine( doc->DocumentElement->InnerText );
   
   // Add white space.     
   XmlNode^ currNode = doc->DocumentElement;
   XmlSignificantWhitespace^ sigws = doc->CreateSignificantWhitespace( "\t" );
   currNode->InsertAfter( sigws, currNode->FirstChild );
   Console::WriteLine();
   Console::WriteLine( "InnerText after..." );
   Console::WriteLine( doc->DocumentElement->InnerText );
}

using System;
using System.Xml;

public class Sample {

  public static void Main() {

      XmlDocument doc = new XmlDocument();
      doc.LoadXml("<author xml:space='preserve'>" +
                  "<first-name>Eva</first-name>"+
                  "<last-name>Corets</last-name>" +
                  "</author>");

      Console.WriteLine("InnerText before...");
      Console.WriteLine(doc.DocumentElement.InnerText);

      // Add white space.
      XmlNode currNode = doc.DocumentElement;
      XmlSignificantWhitespace sigws = doc.CreateSignificantWhitespace("\t");
      currNode.InsertAfter(sigws, currNode.FirstChild);

      Console.WriteLine();
      Console.WriteLine("InnerText after...");
      Console.WriteLine(doc.DocumentElement.InnerText);
  }
}

        Dim sigws As XmlSignificantWhitespace = doc.CreateSignificantWhitespace(ControlChars.Tab)
        currNode.InsertAfter(sigws, currNode.FirstChild)
            
        Console.WriteLine()
        Console.WriteLine("InnerText after...")

    End Sub

備註

此方法是文件物件模型 (DOM) 的 Microsoft 延伸模組。 當您想要手動格式化檔時，會使用它。

雖然這個方法會在文件的內容中建立新的物件，但它不會自動將新物件新增至檔樹狀結構。 若要新增物件，您必須明確呼叫其中一個節點插入方法。
