python - 获取selenium中具有相同类名的所有值

Question

我想获取具有相同类名的文章的文章名称和url。 问题是，它一次又一次地只打印一条信息，而不是所有文章。

from selenium import webdriver
driver = webdriver.Chrome(r'C:\Users\muhammad.usman\Downloads\chromedriver_win32\chromedriver.exe')
driver.get('https://www.aljazeera.com/news/')
# to get the current location ...
driver.current_url
button = driver.find_element_by_id('btn_showmore_b1_418')
driver.execute_script("arguments[0].click();", button)
content = driver.find_element_by_class_name('topics-sec-block')
print(content)
container = content.find_elements_by_xpath('//div[@class="col-sm-7 topics-sec-item-cont"]')
print(container)
i=0
for i in range(0, 12):
    title = []
    url = []
    heading=container[i].find_element_by_xpath('//div[@class="col-sm-7 topics-sec-item-cont"]/a/h2').text
    link = container[i].find_element_by_xpath('//div[@class="col-sm-7 topics-sec-item-cont"]/a')
    title.append(heading)
    url.append(link.get_attribute('href'))
    print(title)
    print(url)
    i += 1
names = driver.find_elements_by_css_selector('div.topics-sec-item-cont')
for name in names:

    heading=name.find_element_by_xpath('//div[@class="col-sm-7 topics-sec-item-cont"]/a/h2').text
    link = name.find_element_by_xpath('//div[@class="col-sm-7 topics-sec-item-cont"]/a')
    print(heading)
    print(link.get_attribute('href'))

Answer 1

使用 Selenium 和 BeautifulSoup

from selenium import webdriver
from bs4 import BeautifulSoup

driver = webdriver.Chrome('C:/chromedriver_win32/chromedriver.exe')
driver.get('https://www.aljazeera.com/news/')
# to get the current location ...
driver.current_url
button = driver.find_element_by_id('btn_showmore_b1_418')
driver.execute_script("arguments[0].click();", button)
content = driver.find_element_by_class_name('topics-sec-block')
print(content)

soup = BeautifulSoup(driver.page_source, 'html.parser')
container = soup.select('div.topics-sec-item-cont')

titleList = []
urlList = []
for item in container:
    heading=item.find('h2').text
    link = item.find('a')['href']
    titleList.append(heading)
    urlList.append(link)
    print('HEADLINE: %s\nUrl: https://www.aljazeera.com%s\n' %(heading, link) + '-'*70 + '\n' )



driver.close()

输出:
