Exemplos

O exemplo de código a seguir demonstra os manipuladores de eventos para o AfterInsert e BeforeDelete eventos. Esses manipuladores de eventos exibir uma caixa de mensagem antes de um XMLNode é excluído do documento e após um XMLNode é adicionado ao documento. O exemplo também usa o RemoveChild método para excluir um nó e aumentar programaticamente a BeforeDelete evento. Este exemplo assume que o documento corrente contém uma XMLNode chamada CustomerNode que contém um nó filho chamado CustomerDateNode.
