我从这个HTML中抓取了多个数据点。给我带来麻烦的是“接受业务来自：”和“业务类”的价值观。我可以获得“接受业务来自：”的价值，无论它出现在哪个订单中：
try:
li_area = company.find('ul', class_='result-info info-cov-' +
str(company_counter) + ' cc')
li_stuff = li_area.find_all('li')
for li in li_stuff:
if li.strong.text.strip() == 'Accepts Business From:':
business_final = li.find('li').text.strip()
except AttributeError:
pass
注意：“company”变量是包含我上面粘贴的html的beautifulsoup对象。
注意：页面上每个记录的类名都会更改 - 我只在HTML示例中包含了一条记录，以保持一些简洁的外观。
当我尝试相同的代码块时，这次用'Accepts Business From:'替换li.strong.text.strip（）== 'Classes of business'，但代码似乎没有检测到那个强标记，只是'接受Business From：'。我的for循环是不正确的，而不是实际迭代每个包含这些不同强标签的<li>标签？难道这个强大标签的真正价值与“业务类别”不同吗？ （我确实直接从网站的html中复制了这个值）。
您可以提供的任何帮助非常感谢
你为'Accepts Business From:'而不是'Classes of business'获取文本的原因是你在错误的地方使用try-except。
在for li in li_stuff:循环的第二次迭代中，li变成<li>U.S.A</li>，因为没有AttributeError标记，所以它会抛出li.strong来调用<strong>。并且，根据您当前的try-except，错误是在for循环外部捕获并且是passed。因此，循环不会达到第三次迭代，它应该获取“业务类”的文本。
要在捕获错误后继续循环，请使用：
for li in li_stuff:
try:
if li.strong.text.strip() == 'Accepts Business From:':
business_final = li.find('li').text.strip()
print('Accepts Business From:', business_final)
if li.strong.text.strip() == 'Classes of business':
business_final = li.find('li').text.strip()
print('Classes of business:', business_final)
except AttributeError:
pass # or you can use 'continue' too.
输出：
Accepts Business From: U.S.A
Classes of business: Engineering
但是，由于“业务类”存在许多值，您可以将代码更改为此以获取所有值：
if li.strong.text.strip() == 'Classes of business':
business_final = ', '.join([x.text.strip() for x in li.find_all('li')])
print('Classes of business:', business_final)
输出：
Accepts Business From: U.S.A
Classes of business: Engineering, NM General Liability (US direct), Property D&F (US binder), Terrorism
