XmlTextWriter::Indentation Property
.NET Framework (current version)
Gets or sets how many IndentChars to write for each level in the hierarchy when Formatting is set to Formatting.Indented.
Assembly: System.Xml (in System.Xml.dll)

Starting with the .NET Framework 2.0, we recommend that you create XmlWriter instances by using the XmlWriter::Create method and the XmlWriterSettings class to take advantage of new functionality. |
Indentation is performed on following node types: DocumentType, Element, Comment, ProcessingInstruction, and CDATASection. All other node types are not affected. The XmlTextWriter does not indent the internal DTD subset. However, you could do the following to apply formatting to the internal DTD subset.
String name = "Employees";
String pubid = null;
String sysid = null;
String subset =
@"
<!ELEMENT Employees (Employee)+>
<!ELEMENT Employee EMPTY>
<!ATTLIST Employee firstname CDATA #REQUIRED>
<!ENTITY Company 'Microsoft'>]>
";
XmlTextWriter tw = new XmlTextWriter(Console.Out);
tw.WriteDocType(name, pubid, sysid, subset);
The following example writes an XML fragment.
#using <System.Xml.dll> using namespace System; using namespace System::IO; using namespace System::Xml; int main() { //Create a writer to write XML to the console. XmlTextWriter^ writer = nullptr; writer = gcnew XmlTextWriter( Console::Out ); //Use indentation for readability. writer->Formatting = Formatting::Indented; writer->Indentation = 4; //Write an element (this one is the root). writer->WriteStartElement( "book" ); //Write the title element. writer->WriteStartElement( "title" ); writer->WriteString( "Pride And Prejudice" ); writer->WriteEndElement(); //Write the close tag for the root element. writer->WriteEndElement(); //Write the XML to file and close the writer. writer->Close(); }
