У меня возникли проблемы с SAX Parser, где он не извлекает полный XML-документ. Я вижу, что это происходит из списка, так как только 1 запись добавляется в список, когда действительно должно быть 3 записи.SAX Parser не отображает полный XML
Может ли кто-нибудь решить проблему, разрешив отображение всех трех записей? Спасибо.
