Попытка исправить colspans HTML-таблицы и rowspans Java

/ 12 июня 2018

Я пытаюсь преобразовать HTML-таблицу в 2-мерный массив с интервалами строк и колспанами в Java.Я нашел решение с помощью Java 8 stream API Извлечение данных из сложных таблиц HTML в 2d массив в Java .

Но мне нужно решение без стримера.Я почти получил решение, но иногда я получаю нулевое значение в некоторых ячейках.

код: 

private static String[][] tableFix2(Elements trElements){
    String table[][] = new String[trElements.first().select("td").size()] 
    [trElements.size()];



    for (int tr = 0; tr < trElements.size(); tr++){
        Elements tdElements = trElements.get(tr).select("td");


        for (int td = 0; td < tdElements.size();td++) {
            Element tdEl = tdElements.get(td);
            String tdElString = tdEl.text();
            //System.out.println(tdElString);

            int colspan = tdEl.attr("colspan").equals("") ? 1 : Integer.parseInt(tdEl.attr("colspan"));
            int rowspan = tdEl.attr("rowspan").equals("") ? 1 : Integer.parseInt(tdEl.attr("rowspan"));

            if (colspan > 1 && rowspan <= 1) {

                for (int c = td; c < td + rowspan; c++) {
                    if (table[c][tr] == null)
                        table[c][tr] = tdElString;
                }


            } else if (rowspan > 1 && colspan <= 1) {

                for (int r = tr; r < tr + rowspan; r++) {
                    if (table[td][r] == null)
                        table[td][r] = tdElString;
                }


            } else if (rowspan > 1 && colspan > 1) {
                for (int r = tr; r < tr + rowspan; r++) {
                    for (int c = td; c < td + colspan; c++) {
                        if (table[c][r] == null)
                            table[c][r] = tdElString;
                    }
                }

            } else {
                if (table[td][tr] == null)
                    table[td][tr] = tdElString;
            }
        }

    }
    System.out.println(Arrays.deepToString(table));


    return table;
}

trElements - это ввод этой функции, я использовал Jsoup, чтобы получить все элементы trтаблицы

Моя таблица:

enter image description here

Вывод: 

[[A, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10], 
[B, 8:25 - 7:40, 8:30-9:15, 9:20-10:05, 10:25-11:10, 11:15-12:00, 12:05-12:50, 13:10-13:55, 14:00-14:45, 14:50-15:35, 15:40-16:25], 
[C, , classes,classes, , , , , , , ], 
[D, homework,homework, , , , , , , , ], 
[E, , , , , , , , , , ], 
[F, , , , , , , , , , ], 
[G, , , , playing,playing, , , , , ], 
[H, , null, null, sleeping,sleeping, , , , , ]]

Просто посчитайте количество тдс в 3-м и 4-м ряду, и вы получите ответ.Вы выполняете только до tdlist.length.В вашем входе недостаточно столбцов для некоторых строк.
