Python BeautifulSoup：从div标记检索文本

Question

我是网页刮刮的新手。我正在使用美丽的汤提取谷歌播放商店。但是，我坚持从div标记中检索文本。Div标记如下所示：

a = <`div class="LVQB0b"><div class="QoPmEb"></div><div><span class="X43Kjb">Education.com</span><span class="p2TkOb">August 15, 2019</span></div>Thanks for your feedback. We are sorry to hear you're having trouble with the app. This is a known issue and our team has fixed it. Please restart the app and let us know at [e-mail] if you have any further trouble. Thanks!</div>` 

我想检索从“谢谢你的反馈”开始的文本。我使用以下代码检索文本：

response = a.find('div',{'class':'LVQB0b'}).get_text()

但是，上面的命令也返回不需要的文本，即'education.com'和日期。我不确定如何从没有类名的div标记中检索文本，如上面的示例所示。等待你的指引。

Answer 1

也可以使用next_sibling或find_next_sibling(text=true)

from bs4 import BeautifulSoup

html= '''<div class="LVQB0b"><div class="QoPmEb"></div><div><span class="X43Kjb">Education.com</span><span class="p2TkOb">August 15, 2019</span></div>Thanks for your feedback. We are sorry to hear you're having trouble with the app. This is a known issue and our team has fixed it. Please restart the app and let us know at [e-mail] if you have any further trouble. Thanks!</div>'''
soup = BeautifulSoup(html, 'html.parser')
print(soup.find('div',class_='QoPmEb').find_next('div').next_sibling)

from bs4 import BeautifulSoup

html= '''<div class="LVQB0b"><div class="QoPmEb"></div><div><span class="X43Kjb">Education.com</span><span class="p2TkOb">August 15, 2019</span></div>Thanks for your feedback. We are sorry to hear you're having trouble with the app. This is a known issue and our team has fixed it. Please restart the app and let us know at [e-mail] if you have any further trouble. Thanks!</div>'''
soup = BeautifulSoup(html, 'html.parser')
print(soup.find('div',class_='QoPmEb').find_next('div').find_next_sibling(text=True))

Answer 2

不需要的文本是 元素的一部分。您可以找到这些元素并从结果中删除它们的文本

response = a.find('div',{'class':'LVQB0b'}).get_text()
unwanted = a.select('.LVQB0b span')
for el in unwanted:
    response = response.replace(el.get_text(), '')

Answer 3

使用查找(text=true,recursive=false)

例：

from bs4 import BeautifulSoup

s = '''<div class="LVQB0b"><div class="QoPmEb"></div><div><span class="X43Kjb">Education.com</span><span class="p2TkOb">August 15, 2019</span></div>Thanks for your feedback. We are sorry to hear you're having trouble with the app. This is a known issue and our team has fixed it. Please restart the app and let us know at [e-mail] if you have any further trouble. Thanks!</div>'''    
html = BeautifulSoup(s, 'html.parser')
print(html.find('div',{'class':'LVQB0b'}).find(text=True, recursive=False))

输出：

Thanks for your feedback. We are sorry to hear you're having trouble with the app. This is a known issue and our team has fixed it. Please restart the app and let us know at [e-mail] if you have any further trouble. Thanks!
