  根据我的理解，您可以按类过滤所需的元素：

  [item.get_text() for item in soup.select("span.header_text")]
  

  ---

  完整的工作示例代码：

  from bs4 import BeautifulSoup
  
  data = """
  <div id="smi-summary-items">
      <div id="smi-price-string">&euro;230,000</div>
      <span class="header_text"> Detached House</span><span class="bar">&nbsp;|&nbsp;</span><span class="header_text">3 Beds</span><span class="bar">&nbsp;|&nbsp;</span><span class="header_text">2 Baths</span>
      <!-- Text_Link_Full_Ad_Unit -->
      <div id='dfp-text_link_full_ad_unit' class='sale'>
          <script type='text/javascript'>
              googletag.cmd.push(function()
                  {
                      googletag.display('dfp-text_link_full_ad_unit');
                  }
              );
          </script>
      </div>"""
  soup = BeautifulSoup(data, "html.parser")
  print([item.get_text(strip=True) for item in soup.select("span.header_text")])
  

  这产生：

  ['Detached House', '3 Beds', '2 Baths']

  以下代码适用于从网站的span类中提取文本的某些元素

  >>> from bs4 import BeautifulSoup
  >>> import re
  >>> content = """<h1>2 Some address</h1>
  ...                 </div>
  ...                 <div id="smi-summary-items">
  ...                     <div id="smi-price-string">&euro;230,000</div>
  ...                     <span class="header_text"> Detached House</span>
  <span class="bar">&nbsp;|&nbsp;</span><span class="header_text">3 
  Beds</span><span class="bar">&nbsp;|&nbsp;</span><span class="header_text">2 
  Baths</span>
  ...                     <!-- Text_Link_Full_Ad_Unit -->
  ...                     <div id='dfp-text_link_full_ad_unit' class='sale'>
  ...                         <script type='text/javascript'>
  ...                             googletag.cmd.push(function()
  ...                                 {
  ...                                     googletag.display('dfp-
  text_link_full_ad_unit');
  ...                                 }
  ...                             );
  ...                         </script>
  ...                     </div>"""
  
  >>> soup = BeautifulSoup(content, "html.parser")
  >>> req = soup.find_all("span", {"class":"header_text"})
  >>> print(req)
  [<span class="header_text"> Detached House</span>, <span 
  class="header_text">3 Beds</span>, <span class="header_text">2 Baths</span>]
  >>> x23 = []
  >>> for i in req:
  ...     x23.append(i.get_text())
  ...
  >>> print(x23)
  [' Detached House', '3 Beds', '2 Baths']
