我希望＆＃34;中的数据也列在＆＃34;类别。即：
Also Listed in
Pubs
Pizza Outlets
Restaurants
Lounge Bars
Microbrewery Pubs
Nightlife Restaurants
Foodie Delight
more...
我尝试使用：
also_listed_in=bSoup.findAll("a", { "onclick" : "_ct('alsocat', 'dtpg', '17592186044416');" })
我能够获得所需的数据。但问题是＆＃34; a＆＃34;标签，即onclick = _ct（＆＃39; alsocat＆＃39;，＆＃39; dtpg＆＃39;，＆＃39; 17592186044416＆＃39;） 不断改变同一种不同的网址。但我观察到 _ct（＆＃39; alsocat＆＃39;，＆＃39; dtpg＆＃39; _ct的一部分（＆＃39; alsocat＆＃39;， ＆＃39; dtpg＆＃39;，＆＃39; 17592186044416＆＃39;）对于所有类似的网址都是相同的。 请帮我获取所需的数据。
答案 0 :(得分：1)
您可以使用未更改的onclick文本部分来获得您想要的内容：
from bs4 import BeautifulSoup
import re
soup = BeautifulSoup(html)
print(soup.find_all("a",onclick=re.compile(r"_ct\('alsocat', 'dtpg'")))
如果_ct('alsocat'对于这些网址是唯一的，那么您可以使用css startswith selector：
print(soup.select("a[onclick^=_ct('alsocat']"))
