我想在網站https://www.fed.cuhk.edu.hk/cri/faculty/prof-bai-barry/上吸引期刊資訊。
但是，當我嘗試使用以下方法時，它會吸引我不想獲得的所有資訊，例如Selected Research and Development Projects with layer。ol
for ol in soup.select(".ar-faculty-section-content ol li"):
它將回傳ol類名中的所有內容".ar-faculty-section-content"。
我期望得到的是只獲取標簽ol下的內容。<b> Refereed Journal articles </b> 我該如何處理？
uj5u.com熱心網友回復：
在示例中使用css selectors通過其文本查找元素并使用它來adjacent sibling combinator選擇：olli
for e in soup.select('b:-soup-contains("Refereed Journal articles") ol li'):
print(e.text)
例子
import requests
from bs4 import BeautifulSoup
headers = {'User-Agent': 'Mozilla/5.0'}
r = requests.get('https://www.fed.cuhk.edu.hk/cri/faculty/prof-bai-barry/', headers=headers)
soup = BeautifulSoup(r.text)
for e in soup.select('b:-soup-contains("Refereed Journal articles") ol li'):
print(e.text)

編輯
事實上，并非所有網站都<b>具有上述方法的文本Refereed Journal articles以空串列結尾。
如果目標是獲取所有出版物，則可以選擇<h5>with textSelected Publications并general sibling combinator結合 with nth-of-type()：
for e in soup.select('h5:-soup-contains("Selected Publications") ~ ol:nth-of-type(1) li'):
print(e.text)
