使用BeautifulSoup4从嵌套span标签提取指定文本的问题

以下几种方式可以单独提取出「Felix Wong」：

• 方法1：直接获取父span的文本节点
  目标名称是父<span>的直接子文本节点，可通过contents访问第一个子元素，再去除多余空格：

  from bs4 import BeautifulSoup
  
  html = '<span>Felix Wong <span class="drivers">+3 drivers</span></span>'
  soup = BeautifulSoup(html, 'html.parser')
  
  parent_span = soup.find('span')
  name = parent_span.contents[0].strip()
  print(name)  # 输出 Felix Wong
  

• 方法2：移除嵌套子标签后提取文本
  先找到并删除嵌套的<span class="drivers">标签，再用get_text()获取父标签的剩余文本：

  from bs4 import BeautifulSoup
  
  html = '<span>Felix Wong <span class="drivers">+3 drivers</span></span>'
  soup = BeautifulSoup(html, 'html.parser')
  
  parent_span = soup.find('span')
  child_span = parent_span.find('span', class_='drivers')
  child_span.decompose()  # 移除子标签
  name = parent_span.get_text().strip()
  print(name)  # 输出 Felix Wong
  

• 方法3：通过stripped_strings迭代取第一个元素
  stripped_strings会迭代标签下所有非空白文本节点，取第一个即可得到目标名称：

  from bs4 import BeautifulSoup
  
  html = '<span>Felix Wong <span class="drivers">+3 drivers</span></span>'
  soup = BeautifulSoup(html, 'html.parser')
  
  parent_span = soup.find('span')
  name = next(parent_span.stripped_strings)
  print(name)  # 输出 Felix Wong
