您可以使用 soup.find('div', {'itemprop': 'datePublished'})选择 div带有 itemprop 的元素datePublished .

from bs4 import BeautifulSoup

content = '''<div class="details-wrapper apps-secondary-color">
    <div class="details-section metadata">
        <div class="details-section-heading">
         <div class="details-section-contents">
             <div class="meta-info">
                 <div class="title">Updated</div>
                 <div class="content" itemprop="datePublished">March 7, 2016</div>
                 </div>
                 <div class="meta-info">
                 <div class="meta-info">
                 <div class="meta-info">
<div class="meta-info">
