无法获取跨度类文本

如何解决无法获取跨度类文本

请找到附件图片。我想获取图像中突出显示的部分，我想获取此属性 1 · Trending,#tuesdaymotivations,7,750 Tweets .

请指教。获取的 URL=https://twitter.com/explore/tabs/trending

from selenium import webdriver

url = 'https://twitter.com/explore/tabs/trending'

# scrolling and scraping tweets

driver = webdriver.Chrome('/chromedriver')
driver.get(url)

trends = driver.find_element_by_xpath('//div[@data-testid="trends"]')
trend = trends[0]
trend.find_element_by_xpath('.//span').text

输出：

  File "/home/PycharmProject/Twitter_trending/ss.py",line 13,in <module>
    trends = driver.find_element_by_xpath('//div[@data-testid="trends"]')

解决方法

尝试使用 JavaScript 获取文本。使用此代码。

span = trend.find_element_by_xpath('.//span')
text = driver.execute_script("return arguments[0].innerText",span)

此方法还可以提供来自嵌套元素的文本。仍然无法正常工作，然后尝试使用 css 选择器而不是 xpath。

trends = driver.find_elements_by_css_selector('div[data-testid="trends"]')
trend = trends[0]
span = trend.find_element_by_xpath('.//span')
text = driver.execute_script("return arguments[0].innerText",span)
