XmlDocument.Load Method (TextReader)

Loads the XML document from the specified TextReader.

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

Public Overridable Sub Load ( _
	txtReader As TextReader _


Type: System.IO.TextReader

The TextReader used to feed the XML data into the document.


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


The Load method always preserves significant white space. The PreserveWhitespace property determines whether or not insignificant white space, that is white space in element content, is preserved. The default is false; white space in element content is not preserved.

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.

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

The following example uses the StringReader class to load a string of XML data into the XmlDocument object.

Imports System
Imports System.IO
Imports System.Xml

public class Sample 

  public shared sub Main() 

    ' Create the XmlDocument. 
    Dim doc as XmlDocument = new XmlDocument()
    Dim xmlData as string = "<book xmlns:bk='urn:samples'></book>"

    doc.Load(new StringReader(xmlData))

    ' Create a new element and add it to the document. 
    Dim elem as XmlElement = doc.CreateElement("bk", "genre", "urn:samples")
    elem.InnerText = "fantasy"

    Console.WriteLine("Display the modified XML...")

  end sub
end class
