        Console.WriteLine("** XML validation exception: {0}", xe.Message);
        return;
        }

// Display a property of the resonstituted custom culture.
    Console.WriteLine(msg3, cib2.CultureName);

// At this point you could call the Register method and make the reconstituted
// custom culture available to other applications. The mySavedCARIB.xml file
// remains on your computer.

Comentários

O xmlFileName parâmetro especifica um nome de arquivo que contém a representação XML de um CultureAndRegionInfoBuilder objeto . O formato do arquivo XML é chamado LDML (Locale Data Markup Language) versão 1.1. Um novo CultureAndRegionInfoBuilder objeto é criado e inicializado com os dados em xmlFileName. O Save método executa a operação inversa do CreateFromLdml método .

No arquivo LDML, as propriedades de uma cultura são especificadas como elementos filho do <special> elemento na <identity> seção . Um valor de propriedade normalmente é especificado pelo atributo do type elemento. Por exemplo, o trecho a seguir de um arquivo LDML define o pai de uma cultura como a cultura neutra em inglês.

<identity>
   <version number="1.1">ldml version 1.1</version>
   <generation date="2012-05-16" />
   <special xmlns:msLocale="http://schemas.microsoft.com/globalization/2004/08/carib/ldml">
      <!-content removed -->
      <msLocale:parentName type="en" />
      <!-content removed -->
   </special>
</identity>

Para obter mais informações sobre o padrão LDML, consulte Padrão Técnico Unicode nº 35, "Linguagem de Marcação de Dados de Localidade (LDML)" no site do Unicode Consortium.
