Noch eine Regex. Bild von Markdown bekommen, abgehört, wenn Markdown innerhalb

Question

Ich versuche, Bilder Informationen aus einem Wiki zu bekommen, habe ich eine funktionierende Regex, aber ich scheitere, wenn die Beschreibung auch Markdown hat.

Format der Bilder auf Abschlag:

//[[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]] 

{{Hauptartikel | [[Christian Anarchismus]] und [[Anarchismus und Religion]]}}

Hier ist die versucht: https://regex101.com/r/pD6nF8/1

Ich versuche so etwas wie:

// \[\[Image:(.*?)\|(.*?)\|(.*?)\|(.*?)\|\[*(.*?)\|*(.*?)\]* 
$re = "/\\[\\[Image:(.*?)\\|(.*?)\\|(.*?)\\|(.*?)\\|\\[*(.*?)\\|*(.*?)\\]*/i"; 

Es sollte 14 für diesen Test finden aber ich bekomme 11 so weit, oder wenn ich die 14 bekomme, bekomme ich auch ein paar Geräusche wie]] oder nur Teile der Beschreibung ...

Wie kann ich den optionalen Fall einbeziehen, so etwas zu haben? (. *?)]] im letzten Teil?

Answer 1

Sie können die verschachtelten Teile definieren, bevor, diese Art von Syntax:

$pattern = '~ 
# definitions 
(?(DEFINE) 
    (?<nested> \[\[ [^][]*+ (?:\[\[ \g<nested> ]] [^][]*)*+ ]]) 
    (?<part> [^][|]*+ (?: \g<nested> [^][|]*)*+   ) 
) 
# main pattern 
\[\[ Image: (\g<part>) \| (\g<part>) \| (\g<part>) \| (\g<part>) \| (\g<part>) ]] 
~ix'; 

demo

Natürlich können Sie genauer sein. Wenn Sie bereits wissen, dass der vierte Teil die Größe ist, können Sie es ersetzen:

\[\[ Image: (\g<part>) \| (\g<part>) \| (\g<part>) \| (\d+ px) \| (\g<part>) ]] 

Sie sind auch frei, um einig Teil optional zu machen, wenn erforderlich (zum Beispiel mit dem Ausrichtungsparameter, die weggelassen werden können):

\[\[ Image: (\g<part>) \| (\g<part>) (?:\| (\g<part>))? \| (\d+ px) \| (\g<part>) ]] 

Oder Sie können sagen, dass alle Parameter sind optional und kann nur einmal vorkommen, aber in diesem Fall müssen Sie genau sein:

~ 
(?(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

Answer 2

Ok, wenn ich es richtig verstehe, wollen Sie nur Bilder mit Styling, ohne Beschreibung.

Also ich denke, das funktionieren könnte für Sie

\[\[Image:.*?[jpg|svg][^\s]+(?=\|) 

Dann] fügen Sie einfach], um Ihre Spiele.

Answer 3

Beschreibung

Dies ist mehrzeilige regex folgende Fähnchen: Ignorieren Sie Leerzeichen, Global, und Case Insensitive

[[]{2}Image: 
([^|]*\.(?:jpe?g|svg))[|] 
([^|]*)[|] 
    ((?:[[]{2}[^\]]*\]\]|[^|[])*)[|] 
(?:((?:[[]{2}[^\]]*\]\]|[^|[])*)[|])? 
    ((?:[[]{2}[^\]]*\]\]|(?:(?!\]|\|).))*) 
(?:[|]|\]\]) 

Dieser reguläre Ausdruck wird wie folgt vor:

• finden Sie die [[image:....]] Teilstrings aus m Ihr Beispieltext
• erfordert, dass das Bild mit einem der folgenden .jpg, .jpeg oder .svg endet. Sie können dieses Verhalten entfernen, indem Sie das \.(?:jpe?g|svg)-Konstrukt entfernen.
• analysieren die verschiedenen | abgegrenzte Felder
• Vermeiden schwierigen Randfällen in den letzten mehreren Feldern, die zusätzliche Auszeichnungs

nahm ich mir die Freiheit, alle 14 Spiele von ziehen, aber die live demo hat immer noch Ihre ursprüngliche Text

Answer 4

Was ist, wenn Sie sie nur mit dieser Regex übereinstimmen: \[\[Image\:(.*)\]\] und dann teilen Sie jedes Ergebnis einfach mit |. Ich weiß nicht, ob es eine gute Idee ist, aber es schadet nichts.
