Еще одно регулярное выражение. Получение изображения из уценки, прослушивается, если уценка внутри
Я пытаюсь получить информацию об изображениях из вики, у меня есть работающее регулярное выражение, но у меня не получается, когда в описании также есть уценка.
Формат изображений по уценке:
//[[Image:WilliamGodwin.jpg|thumb|right|150px|William Godwin]]
//[[Image:JohannMost.jpg|left|150px|thumb|[[Johann Most]] was an outspoken advocate of violence]]
//[[Image:CNT-armoured-car-factory.jpg|right|thumb|270px|[[Spain]], [[1936]]. Members of the [[CNT]] construct [[armoured car]]s to fight against the [[fascist]]s in one of the [[collectivisation|collectivised]] factories.]]
[[Image:CNT_tu_votar_y_ellos_deciden.jpg|thumb|175px|CNT propaganda from April 2004. Reads: Don't let the politicians rule our lives/ You vote and they decide/ Don't allow it/ Unity, Action, Self-management.]]
[[Image:Flag of Anarcho syndicalism.svg|thumb|175px|The red-and-black flag, coming from the experience of anarchists in the labour movement, is particularly associated with anarcho-syndicalism.]]
[[Image:LeoTolstoy.jpg|thumb|150px|[[Leo Tolstoy|Leo Tolstoy]] 1828-1910]]
{{основные статьи | [[Христианский анархизм]] и [[Анархизм и религия]]}}
Вот попытки: https://regex101.com/r/pD6nF8/1
Я пытаюсь что-то вроде:
// \[\[Image:(.*?)\|(.*?)\|(.*?)\|(.*?)\|\[*(.*?)\|*(.*?)\]*
$re = "/\\[\\[Image:(.*?)\\|(.*?)\\|(.*?)\\|(.*?)\\|\\[*(.*?)\\|*(.*?)\\]*/i";
Он должен найти 14 для этого теста, но я пока получаю 11, или, если я получаю 14, я получаю также некоторый шум вроде]] или просто части описания …
Как я могу включить необязательный случай с чем-то вроде этого [[(. *?)]] Внутри последней части?
Решение
Вы можете определить вложенные части раньше, используя такой синтаксис:
$pattern = '~
# definitions
(?(DEFINE)
(?<nested> \[\[ [^][]*+ (?:\[\[ \g<nested> ]] [^][]*)*+ ]] )
(?<part> [^][|]*+ (?: \g<nested> [^][|]* )*+ )
)
# main pattern
\[\[ Image: (\g<part>) \| (\g<part>) \| (\g<part>) \| (\g<part>) \| (\g<part>) ]]
~ix';
Очевидно, вы можете быть более точным. Если вы уже знаете, что четвертая часть имеет размер, вы можете заменить ее:
\[\[ Image: (\g<part>) \| (\g<part>) \| (\g<part>) \| (\d+ px) \| (\g<part>) ]]
Вы также можете сделать некоторую часть необязательной, если это необходимо (например, с параметром выравнивания, который можно опустить):
\[\[ Image: (\g<part>) \| (\g<part>) (?:\| (\g<part>) )? \| (\d+ px) \| (\g<part>) ]]
Или вы можете сказать, что все параметры являются необязательными и могут встречаться только один раз, но в этом случае вам нужно быть точным:
~
(?(DEFINE)
(?<nested> \[\[ [^][]*+ (?: \[\[ \g<nested> ]] [^][]* )*+ ]] )
(?<part> [^][|]*+ (?: \g<nested> [^][|]* )*+ )
)
\[\[Image: (?<name> [^]|]* )
(?:
\|
(?: (?<align> left|right|center ) |
(?<type> thumb ) |
(?<size> \d+[a-z]{0,3} ) |
(?<description> \g<part> )
)
)*
]]
~ix
Другие решения
Это многострочное регулярное выражение использует следующие флаги: Игнорировать пробелы, Глобальные и Без учета регистра
[[]{2}Image:
([^|]*\.(?:jpe?g|svg))[|]
([^|]*)[|]
((?:[[]{2}[^\]]*\]\]|[^|[])*)[|]
(?:((?:[[]{2}[^\]]*\]\]|[^|[])*)[|])?
((?:[[]{2}[^\]]*\]\]|(?:(?!\]|\|).))*)
(?:[|]|\]\])
Это регулярное выражение будет делать следующее:
- Найти
[[image:....]]подстроки из вашего образца текста - требует, чтобы изображение заканчивалось одним из следующих
.jpg,.jpeg, или же.svg, Вы можете удалить это поведение, удалив\.(?:jpe?g|svg)построить. - разбирать различные
|поля с разделителями - избегайте сложных крайних случаев в последних нескольких полях, которые могут содержать дополнительную разметку

Хорошо, если я правильно понял, вы хотите только изображения со стилем, без описания.
Так что я думаю, что это может сработать для вас
\[\[Image:.*?[jpg|svg][^\s]+(?=\|)
Затем просто добавьте]] к своим матчам.
Что если вы просто сопоставите их с этим регулярным выражением: \[\[Image\:(.*)\]\] а затем просто разделить каждый результат с |, Не знаю, хорошая ли это идея, но в попытках нет вреда.
