<li class="result-card job-result-card result-card--with-hover-state job-card__contents--active" data-id="1946843843" data-entity-urn="urn:li:jobPosting:1946843843" data-search-id="e2f62398-982f-463e-9685-9064dfa810eb" data-tracking-id="UDB/ibIoQvCk1l54VneerA==" data-column="1" data-row="1">

我在 job_posting 中有单独的容器，我正在尝试访问 data-id 并获取编号...

这是我的代码

job_postings 中的工作：

        #Scrapping info from main search page
        
        try:
            job_id = job.find_all("li",{"class"})['data-id']
            
        except:
            job_id = 'No data available'
        job_ids.append(job_id)

你可以使用下面的方法

from bs4 import BeautifulSoup
html = '''<li class="result-card job-result-card result-card--with-hover-state job-card__contents--active" data-id="1946843843" data-entity-urn="urn:li:jobPosting:1946843843" data-search-id="e2f62398-982f-463e-9685-9064dfa810eb" data-tracking-id="UDB/ibIoQvCk1l54VneerA==" data-column="1" data-row="1">'''
soup = BeautifulSoup(html, 'html.parser')
result = [item['data-id'] for item in soup.find_all('li', attrs={'data-id' : True})]
print(result)
Output:-
['1946843843']
