using namespace System::Xml;
int main()
{
//Load XML data which includes white space, but ignore
//any white space in the file.
XmlDocument^ doc = gcnew XmlDocument;
doc->PreserveWhitespace = false;
doc->Load( "book.xml" );
//Save the document as is (no white space).
Console::WriteLine( "Display the modified XML..." );
doc->PreserveWhitespace = true;
doc->Save( Console::Out );
}
using System;
using System.IO;
using System.Xml;
public class Sample
{
public static void Main()
{
//Load XML data which includes white space, but ignore
//any white space in the file.
XmlDocument doc = new XmlDocument();
doc.PreserveWhitespace = false;
doc.Load("book.xml");
//Save the document as is (no white space).
Console.WriteLine("Display the modified XML...");
doc.PreserveWhitespace = true;
doc.Save(Console.Out);
}
}
Imports System.IO
Imports System.Xml
public class Sample
public shared sub Main()
'Load XML data which includes white space, but ignore
'any white space in the file.
Dim doc as XmlDocument = new XmlDocument()
doc.PreserveWhitespace = false
doc.Load("book.xml")
'Save the document as is (no white space).
Console.WriteLine("Display the modified XML...")
doc.PreserveWhitespace = true
doc.Save(Console.Out)
end sub
end class
The example uses the file book.xml
as input.
<!--sample XML fragment-->
<book genre='novel' ISBN='1-861003-78' misc='sale-item'>
<title>The Handmaid's Tale</title>
<price>14.95</price>
</book>
Remarks
This property determines how white space is handled during the load and save process.
If PreserveWhitespace
is true
before Load or LoadXml is called, white space nodes are preserved; otherwise, if this property is false
, significant white space is preserved, white space is not.
If PreserveWhitespace
is true
before Save is called, white space in the document is preserved in the output; otherwise, if this property is false
, XmlDocument
auto-indents the output.
This method is a Microsoft extension to the Document Object Model (DOM).
