Итак, со входными данными покончено. Давайте теперь разберемся с выходными.
Então essa é a entrada. Agora vamos pensar na saída.
И снова вернемся к тому же самому сегменту кода,
Novamente, estamos em busca do mesmo segmento de códigos
который мы пытаемся заменить процедурой.
que estávamos tentando substituir com um procedimento.
Что должны включать в себя выходные данные? Этот вопрос будет посложнее.
E qual deve ser a saída? Esta exige mais atenção.
Нужно определить, что нам важно знать после выполнения кода.
Devemos pensar no que precisamos saber depois que o código rodar.
Нам не удастся напрямую получить доступ к этим переменным, если мы превратим наш код в процедуру.
Não temos acesso às variáveis se estamos criando um procedimento.
Нам нужно получить – в качестве выходных данных –
Precisamos ter, como saídas,
все, что нам понадобится после выполнения процедуры.
tudo o que queremos usar após o procedimento.
Итак, вопрос в том, какими должны быть выходные данные процедуры get_next_target(),
Então, a questão é qual deve ser a saída de "get-next-target",
которой мы собираемся заменить этот код?
o procedimento que vamos definir para substituir esse código.
Первый вариант – на выходе должна быть строка,
A 1ª opção é ter como saída uma string
содержащая значение следующего URL в строке page.
com o valor do próximo URL alvo encontrado na página.
То есть значение, хранящееся в переменной url.
É isso o que a variável "url" contém aqui.
Второй вариант – мы должны подавать на выход и URL, и значение page.
A 2ª opção é ter como saída tanto o URL quanto a página.
Третий – на выходе должны быть URL и значение end_quote,
A terceira é ter como saída tanto o URL quanto o valor de "end_quote",
то есть позиция закрывающей кавычки.
a posição onde termina a citação.
И четвертый вариант – на выходе должно быть значение url
E a 4ª opção é ter como saída o valor de "url",
и значение start_link,
assim como o valor de "start_link".
то есть позиция,
Essa é a posição
с которой начинается ссылка.
onde encontramos o início do link.
