XmlDocument::Load Method (TextReader^)

 

Loads the XML document from the specified TextReader.

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

public:
virtual void Load(
	TextReader^ txtReader
)

Parameters

txtReader
Type: System.IO::TextReader^

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

Exception Condition
XmlException

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

System_CAPS_noteNote

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.

#using <System.Xml.dll>

using namespace System;
using namespace System::IO;
using namespace System::Xml;
int main()
{

   // Create the XmlDocument.
   XmlDocument^ doc = gcnew XmlDocument;
   String^ xmlData = "<book xmlns:bk='urn:samples'></book>";
   doc->Load( gcnew StringReader( xmlData ) );

   // Create a new element and add it to the document.
   XmlElement^ elem = doc->CreateElement( "bk", "genre", "urn:samples" );
   elem->InnerText = "fantasy";
   doc->DocumentElement->AppendChild( elem );
   Console::WriteLine( "Display the modified XML..." );
   doc->Save( Console::Out );
}
