When I run your code it selects the outer div, while I'm presuming what your looking for is the inner div. The documentationsays that it selects the "elements that contains the specified text". In this simple html:
当我运行您的代码时，它会选择外部div，而我假设您要寻找的是内部div。该文件说，它选择了“包含指定文本元素”。在这个简单的 html 中：
<div><div><b>Pantry/Catering</b></div></div>
The selector div:contains(Pantry/Catering)matches twice because both contain the text 'Pantry/Catering':
选择器div:contains(Pantry/Catering)匹配两次，因为两者都包含文本“Pantry/Catering”：
<!-- First Match -->
<div><div><b>Pantry/Catering</b></div></div>
<!-- Second Match -->
<div><b>Pantry/Catering</b></div>
The matches are always in that order because jsoup matches from the outside. Therefore .first()always matches the outer div. To extract the inner divyou could use .get(1).
匹配始终按该顺序进行，因为 jsoup 从外部匹配。因此.first()始终匹配外部div. 要提取内部，div您可以使用.get(1).
Extracting the inner divin full:
完全提取内部div：
doc.select("div:contains(Pantry/Catering)").get(1)

好的。弄清楚了。不得不做类似的事情

This should also do the work for you:
这也应该为您完成工作：
doc.selectFirst("div:containsOwn(Pantry/Catering)").text();
Explanation:
解释：
selectFirst(selector) - Helps to avoid using select().first()
selectFirst(selector) - 有助于避免使用 select().first()
containsOwn(text) - A pseudo selector to return elements that directly contain the specified text. The text must appear in the found element, not any of its descendants in contrast with contains(text).
containsOwn(text) - 一个伪选择器，用于返回直接包含指定文本的元素。文本必须出现在找到的元素中，而不是与 contains(text) 相反的任何其后代。
