Die Auswahl nur von Kind-Knoten mit Jsoup?

Derzeit arbeite ich mit einem <ul> element mit einer Menge first-level - <li> Elemente. Ich möchte, um diese Elemente, und nur diese Elemente. Allerdings, wenn ich Sie entweder mit Jsoup-Selektor oder getElementsByTag, es gibt auch <li> Elemente innerhalb dieser first-level - <li> Elemente.

Wie mache ich es so, dass ich nur die erste Ebene <li> Elemente?

Hier der code:

Elements bundleList =  indieGala.select("section.games_bundle_box2")
                        .get(0).select("ul.unlock")
                        .get(0).getElementsByTag("li");

Hier ist der html:

<section class="games_bundle_box2">

              Saira is a puzzle platformer with non-linear gameplay and a whole universe for you to explore. The game is heavily influenced by classic puzzle adventure games and uses a new unique graphical style combining high resolution photography into a lush and mysterious world.

            <p>
              The eponymous Saira is a photographer who specializes in digitally capturing dangerous places and animals across the universe. For reasons unknown, she finds herself as the only remaining person in the entire galaxy. Saira has no weapons, she will use only her mind and agility to progress through seven star systems and over 60 well-crafted puzzles. Over two hours of originally-scored music will help her maintain focus and unlock one of six vastly unique endings.

Sie sollten zeigen Sie Ihren code. Es macht es einfacher für Menschen, um Ihnen zu helfen, das heißt, Sie erhalten auch bessere Antworten. Als Jerry McGuire sagen würde. "Helfen Sie mir helfen Sie". Viel Glück! 🙂
ok getan. code und html in OP.
Nicht sehr verständlich, ich konnte kaum verstehen, was Sie wollen.. jsoup.org/apidocs/org/jsoup/select/Selector.html
"Ich will diese Elemente und nur die Elemente." Welche dieser Elemente ?
ich wusste nicht, hisenberg wurde in der Programmierung nach dem Kochen in "breaking bad". @heisenbergman

Vielleicht habe ich etwas übersehen, aber wie über die Auswahl basiert auf den direkten Abstiegen von ul.unlock? Sie können dies tun, indem > in Ihrem Selektor-Ausdrucks:

parent > child: Kind-Elemente, die stammen direkt von den Eltern, z.B. div.content > p findet p Elemente; und body > * findet die direkte Kinder des body tag (Quelle)

Mithilfe ul.unlock > li sollte es nur wählen die top-level - li Elemente, die Sie möchten, z.B.:
```
ListIterator<Element> bundleList = indieGala.select("section.games_bundle_box2")
    .get(0)
    .select("ul.unlock > li")
    .listIterator();

assert Iterators.size(bundleList) == 5;
```
Ich hoffe, das hilft.
- Keine Antworten bisher herausgefiltert, die sub-Listen. Betrachten Sie die Erstellung und Veröffentlichung einer sscce.
- Ich wusste nicht, interpretieren die Frage so, ich dachte, das problem war, dass die Unterliste <li> Elemente wurden wiederholt, d.h. Sie waren kehrte durch den Aufruf von getElementsByTag waren und auch innerhalb der top-level - <li> Elemente.

Können Sie einfach suchen, Kinder mit dieser -
```
Elements bundleList = indieGala.select("section.games_bundle_box2").first().select("ul.unlock").first().children();
```
Sollte dies schneller sein als das ausführen eines Selektors und in Ihrem Fall geben Ihnen die genauen Ergebnisse, die Sie suchen.

Dadurch erhalten Sie Zugriff auf alle direkten Kinder (li) der ul-tag :

Elemente lis = doc.wählen Sie("Abschnitt.games_bundle_box2").ersten().wählen Sie("ul.entsperren > li");

Ist das, was Sie wollen?
