Question

在XPath之后选择带有类ajaxcourseindentfix的div元素并将其从Prerequisite中分离出来并在先决条件之后给出所有内容。

div = soup.select("div.ajaxcourseindentfix")[0]
" ".join([word for word in div.stripped_strings]).split("Prerequisite: ")[-1]

我的div不仅有先决条件，还有以下分裂点：

先决条件
  核心要求
  核心要求

现在，每当我有先决条件时，上面的XPath工作正常，但无论何时出现上述三个，XPath都会失败并给我全文。

有没有办法在XPath中放置多个分隔符？或者我该如何解决？

此代码是您的问题的解决方案，除非您特别需要XPath，我还建议您查看 BeautifulSoup 文档，了解我使用的方法，您可以找到{{3 }}

在这些情况下，

com.microsoft.sqlserver.jdbc.SQLServerDriver和.next_element非常有用。或.next_sibling我们将获得一台发电机，我们将以我们可以操纵发电机的方式转换或使用它。

.next_elements

解决这两个问题，我们不必使用 CSS选择器和那些奇怪的列表操作。一切都是有机，有效。
