Python 如何获取文本?
例如:Python 如何获取文本?,python,beautifulsoup,Python,Beautifulsoup,例如: <div class=" col-md-8"> <strong>1.</strong> Every quadratic polynomial can have at most </div> <div class=" col-md- 8"> &am
<div class=" col-md-8">
<strong>1.</strong> Every quadratic
polynomial
can have at most
</div>
<div class=" col-md-
8"> (a) If
b<sup>2</sup> – 4ac is a perfect square, the roots are rational.
</div>
1.每二次
多项式的
最多可以有
(a) 如果
b2–4ac是一个完美的正方形,根是有理的。
如何使用find_all方法获取仅包含强标记的div文本?通过升级您制作的内容:
results = []
for b in mcq.find_all('div',class_=" col-md-8"): #here you find all the div of the correct class
if b and b.find_all("strong"): # then you check if there is a "strong" tag inside
results.append(b) # if yes => append it to the final list
试试看。虽然我使用了您提供的内容中的类名,但它们似乎是动态生成的,因此不值得依赖
from bs4 import BeautifulSoup
html_content='''
<div class=" col-md-8">
<strong>1.</strong> Every quadratic
polynomial
can have at most
</div>
<div class=" col-md-
8"> (a) If
b<sup>2</sup> – 4ac is a perfect square, the roots are rational.
</div>
'''
soup = BeautifulSoup(html_content,"lxml")
for items in soup.find_all("div",class_="col-md-8")[0].find_all("strong"):
core_text = ' '.join([item.strip() for item in items.next_sibling.split()])
print(core_text)
您尝试了什么?对于mcq.find_all('div',class=“col-md-8”)中的b,您应该包含您尝试过的代码的最低版本,但在您的答案中不起作用,我们非常感谢它,它使您的帮助更加容易。更多信息:澄清“仅包含强标记的div”:你是指只包含强标记的div,还是仅包含强标记的div?我看到这可能是多行书写的,以更好的注释性,但这在列表理解中可能更优雅。你是对的@D.Everhard故意(太)长;)
