Examples

The following example loads XML into an XmlDocument object and saves it out to a file.

#using <System.Xml.dll>

using namespace System;
using namespace System::Xml;
int main()
{
   
   // Create the XmlDocument.
   XmlDocument^ doc = gcnew XmlDocument;
   doc->LoadXml( "<item><name>wrench</name></item>" );
   
   // Add a price element.
   XmlElement^ newElem = doc->CreateElement( "price" );
   newElem->InnerText = "10.95";
   doc->DocumentElement->AppendChild( newElem );
   
   // Save the document to a file and auto-indent the output.
   XmlTextWriter^ writer = gcnew XmlTextWriter( "data.xml", nullptr );
   writer->Formatting = Formatting::Indented;
   doc->Save( writer );
}

using System;
using System.Xml;

public class Sample {

  public static void Main() {

    // Create the XmlDocument.
    XmlDocument doc = new XmlDocument();
    doc.LoadXml("<item><name>wrench</name></item>");

   // Add a price element.
   XmlElement newElem = doc.CreateElement("price");
   newElem.InnerText = "10.95";
   doc.DocumentElement.AppendChild(newElem);

   XmlWriterSettings settings = new XmlWriterSettings();
   settings.Indent = true;
   // Save the document to a file and auto-indent the output.
   XmlWriter writer = XmlWriter.Create("data.xml", settings);
    doc.Save(writer);
  }
}

Imports System.Xml

public class Sample 

  public shared sub Main() 
 
    ' Create the XmlDocument.
    Dim doc as XmlDocument = new XmlDocument()
    doc.LoadXml("<item><name>wrench</name></item>")

   ' Add a price element.
   Dim newElem as XmlElement = doc.CreateElement("price")
   newElem.InnerText = "10.95"
   doc.DocumentElement.AppendChild(newElem)

   Dim settings As New XmlWriterSettings()
   settings.Indent = True
   ' Save the document to a file and auto-indent the output.
   Dim writer As XmlWriter = XmlWriter.Create("data.xml", settings)
    doc.Save(writer)
  end sub
end class

Remarks

By default the LoadXml method does not preserve white space or significant white space.

This method parses Document Type Definitions (DTDs), but does not do DTD or Schema validation. If you want validation to occur, you can create a validating XmlReader instance by using the XmlReaderSettings class and the Create method. For more information, see the Remarks section of the XmlReader reference page.

If you want to load from a Stream, String, TextReader, or XmlReader, use the Load method instead of this method.

This method is a Microsoft extension to the Document Object Model (DOM).
