.NET Framework Class Library

XmlDocument..::.LoadXml Method

Updated: November 2007

Loads the XML document from the specified string.

Namespace: System.Xml
Assembly: System.Xml (in System.Xml.dll)

Syntax

Visual Basic (Declaration)

Public Overridable Sub LoadXml ( _
    xml As String _
)

Visual Basic (Usage)

Dim instance As XmlDocument
Dim xml As String

instance.LoadXml(xml)

public virtual void LoadXml(
    string xml
)

Visual C++

public:
virtual void LoadXml(
    String^ xml
)

public void LoadXml(
    String xml
)

JScript

public function LoadXml(
    xml : String
)

Parameters

xml: Type: System..::.String
String containing the XML document to load.

Exceptions

Exception	Condition
XmlException	There is a load or parse error in the XML. In this case, the document remains empty.

Remarks

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).

Examples

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

Visual Basic

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 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);

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

Visual C++

#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 );
}

import System.*;
import System.Xml.*;

public class Sample
{
    public static void main(String[] args)
    {
        // Create the XmlDocument.
        XmlDocument doc = new XmlDocument();
        doc.LoadXml("<item><name>wrench</name></item>");

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

        // Save the document to a file and auto-indent the output.
        XmlTextWriter writer = new XmlTextWriter("data.xml", null);
