类型错误"无类型"对象不是可调用的Selenium

Question

代码：

from selenium import webdriver
from bs4 import BeautifulSoup
driver=webdriver.Chrome('H:datascience-pythonseliniumchromedriver.exe')
driver.get('https://www.aljazeera.com/news/')
button = driver.find_element_by_id('btn_showmore_b1_418')
driver.execute_script("arguments[0].click();", button)
content = driver.page_source
soup = BeautifulSoup(content, 'html.parser')
container = soup.select('div.topics-sec-item-cont')
titlelist = []
urllist = []
for items in  container:
    if items is not None:
        title = items.find_element_by_xpath('//div[@class="col-sm-7 topics-sec-item-cont"]/a/h2').text
        url = items.find_element_by_xpath('//div[@class="col-sm-7 topics-sec-item-cont"]/a')
        titlelist.append(title)
        urllist.append(url.get_attribute('href'))
        print(str(titlelist) + 'n')
        print(str(urllist) + 'n')

错误：

Answer 1

title = items.find_element_by_xpath('//div[@class="col-sm-7 topics-sec-item-cont"]/a/h2').text

这行代码中提供的xpath没有返回对象。这个问题的出现只有两个原因：

1. 要么提供的xpath错误
2. 您试图从中提取的div尚未完全加载
