使用Beautiful Soup从网页中提取特定字符串

Question

我有一系列的URL的我正在循环，并希望检索所有在"已知的";页面顶部的行(示例)。然而，并不是每个体育场都有这样的(例子)。

1 Arrowhead Drive, Kansas City, MO 64129
Years Active: 1972-2021 (406 games)
===> Known As: Arrowhead Stadium (1972-2020), GEHA Field at Arrowhead Stadium (2021-2021) <===
Surfaces: astroturf (1972-1993), grass (1994-2021)

这里是代码返回div中的一切，但我不确定如何继续并返回我想要的特定p标签中的文本。

url_base = "https://www.pro-football-reference.com/stadiums/KAN00.htm"
response = requests.get(url_base)
soup = bs(response.text, "html.parser")
div = soup.find("div", {"id":"meta"})

Answer 1

您可以选择<b>标记，文本为"Known As"然后得到下一个文本sibling:

txt = (
soup.select_one('b:-soup-contains("Known As")')
.find_next_sibling(text=True)
.strip()
)
print(txt)

打印:

Arrowhead Stadium (1972-2020), GEHA Field at Arrowhead Stadium (2021-2021)
