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

This method 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 Validating XML Data with XmlReader.

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).

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

Imports System
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)

    ' Save the document to a file and auto-indent the output.
    Dim writer as XmlTextWriter = new XmlTextWriter("data.xml",nothing)
    writer.Formatting = Formatting.Indented
    doc.Save(writer)
  end sub
end class

#using <mscorlib.dll>
#using <System.Xml.dll>
using namespace System;
using namespace System::Xml;

int main()
{
    // Create the XmlDocument.
    XmlDocument* doc = new XmlDocument();
    doc->LoadXml(S"<item><name>wrench</name></item>");

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

    // Save the document to a file and auto-indent the output.
    XmlTextWriter* writer = new XmlTextWriter(S"data.xml",0);
    writer->Formatting = Formatting::Indented;
    doc->Save(writer);
};
