如何使用 bs4 从复选框中获取文本？

Question

我正在尝试从以下站点上勾选（或回答的问题）的框中获取所有标签（文本）。

然而我似乎没有得到任何文本。

此外，我想到的进行抓取的方式是首先收集所有 links - 在右侧，您可以在页面之间切换。这个列表似乎也有 links 次 2...

这是我当前的代码（请参阅其中的 link，也称为 main_url）

import bs4 as bs
from splinter import Browser
import time



executable_path = {'executable_path' :'C:/users/chromedriver.exe'}
browser = Browser('chrome', **executable_path)

main_url = 'https://reporting.unpri.org/surveys/PRI-Reporting-Framework-
2016/0ad07cdc-cfbc-4c5b-a79f-
2b07e93d8521/79894dbc337a40828d895f9402aa63de/html/2/?lang=&a=1'
browser.visit(main_url)
source = browser.html
soup = bs.BeautifulSoup(source, 'lxml')
base_url = main_url[:-51]
urls = []
print(base_url)

for i in soup.find_all('div', class_ = 'accordion-inner n-accordion-link'):
    for j in soup.find_all('a', class_ = 'tooltiper'):
        urls.append(j['href'])

print(urls)

result = []
for k in urls:
    ext = k[8:]
    browser.visit(base_url + ext)
    source1 = browser.html
    soup1 = bs.BeautifulSoup(source1, 'lxml')
    temp_list = []
    print(browser.url)
    for img in soup1.find_all('img', class_ = 'readradio'):
        for t in img['src']:
            if t == '/Style/img/checkedradio.png':
                for x in soup1.find_all('span', class_ = 'title'):
                    txt = str(x.string)
                    temp_list.append(txt)

result.append(temp_list)
print(result)

我得到结果列表的以下输出，其中应该包含文本：

[[], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], [], []]

根据建议更新了代码：

import bs4 as bs
from splinter import Browser
import time



executable_path = {'executable_path' 
:'/users/nichlasrasmussen/documents/webdrivers/phantomjs'}
browser = Browser('phantomjs', **executable_path)

main_url = 'https://reporting.unpri.org/surveys/PRI-Reporting-Framework-
2016/0ad07cdc-cfbc-4c5b-a79f-
2b07e93d8521/79894dbc337a40828d895f9402aa63de/html/2/?lang=&a=1'
browser.visit(main_url)
source = browser.html
soup = bs.BeautifulSoup(source, 'lxml')
base_url = main_url[:-51]
urls = []
print(base_url)

for i in soup.find_all('div', class_ = 'accordion-inner n-accordion-link'):
    for j in soup.find_all('a', class_ = 'tooltiper'):
        urls.append(j['href'])

    print(urls)

result = []
for k in urls:
    ext = k[8:]
    browser.visit(base_url + ext)
    source1 = browser.html
    soup1 = bs.BeautifulSoup(source1, 'lxml')
    temp_list = []
    print(browser.url)
    for label in soup1.find_all('label', class_='radio'):
    t = label.find('img', class_='readradio')
    if 'checkedradio' in t['src']:
        content = soup1.find('span', class_='title')
        temp_list.append(content.text)

result.append(temp_list)
print(result)

Answer 1

您基本上可以只引用 img 和 span.title 元素的父元素，即 label.radio.

无需从根目录开始进行大量循环(soup1)

试试这个：

for label in soup1.find_all('label', class_='radio'):
    t = label.find('img', class_='readradio')
    if t and '/Style/img/checkedradio.png' in t.get('src'):
        content = label.find('span', class_='title')
        temp_list.append(content.text)
