member this.Standalone : string with get, set

Property Value

Valid values are yes if all entity declarations required by the XML document are contained within the document or no if an external document type definition (DTD) is required. If a standalone attribute is not present in the XML declaration, this property returns String.Empty.


The following example creates an XmlDeclaration node and adds it to an XML document.

#using <System.Xml.dll>

using namespace System;
using namespace System::IO;
using namespace System::Xml;
int main()
   // Create and load the XML document.
   XmlDocument^ doc = gcnew XmlDocument;
   String^ xmlString = "<book><title>Oberon's Legacy</title></book>";
   doc->Load( gcnew StringReader( xmlString ) );
   // Create an XML declaration. 
   XmlDeclaration^ xmldecl;
   xmldecl = doc->CreateXmlDeclaration( "1.0", nullptr, nullptr );
   xmldecl->Encoding = "UTF-8";
   xmldecl->Standalone = "yes";
   // Add the new node to the document.
   XmlElement^ root = doc->DocumentElement;
   doc->InsertBefore( xmldecl, root );
   // Display the modified XML document 
   Console::WriteLine( doc->OuterXml );

using System;
using System.IO;
using System.Xml;
public class Sample {

  public static void Main() {
    // Create and load the XML document.
    XmlDocument doc = new XmlDocument();
    string xmlString = "<book><title>Oberon's Legacy</title></book>";
    doc.Load(new StringReader(xmlString));
    // Create an XML declaration. 
    XmlDeclaration xmldecl;
    xmldecl = doc.CreateXmlDeclaration("1.0",null,null);
    // Add the new node to the document.
    XmlElement root = doc.DocumentElement;
    doc.InsertBefore(xmldecl, root);
    // Display the modified XML document 
Imports System
Imports System.IO
Imports System.Xml
public class Sample 

  public shared sub Main() 
    ' Create and load the XML document.
    Dim doc as XmlDocument = new XmlDocument()
    Dim xmlString as string = "<book><title>Oberon's Legacy</title></book>"
    doc.Load(new StringReader(xmlString))
    ' Create an XML declaration. 
    Dim xmldecl as XmlDeclaration 
    xmldecl = doc.CreateXmlDeclaration("1.0",nothing, nothing)
    ' Add the new node to the document.
    Dim root as XmlElement = doc.DocumentElement
    doc.InsertBefore(xmldecl, root)
    ' Display the modified XML document 
  end sub
end class
