python - 如何从谷歌趋势中提取标题/文本并通过 Selenium 和 Python 打印它们

Question

我想从该站点中提取每一行中的不同标题：

https://trends.google.com/trends/trendingsearches/realtime?geo=AR&category=all

我尝试了几次没有运气的尝试。我认为通过按类搜索元素，我会得到所需的文本：

from selenium import webdriver
driver=webdriver.Chrome('path to bin')
driver.get('https://trends.google.com/trends/trendingsearches/realtime?geo=AR&category=all')
hrefs = driver.find_elements_by_class_name('title')
print hrefs
print(len(hrefs))
driver.quit()

提前谢谢各位！琼

Answer 1

你是如此接近！您只需要从标题中获取文本，试试这个：

from selenium import webdriver

driver=webdriver.Chrome('path to bin')
driver.get('https://trends.google.com/trends/trendingsearches/realtime?geo=AR&category=all')
Titles = driver.find_elements_by_class_name('title')
for title in Titles:
    print(title.text)
driver.quit()

@PixelEinstein 的回答将完美地满足您的要求。但作为最佳实践的一部分，您应该始终最大化浏览器窗口并诱导WebDriverWait让元素首先可见，然后提取其中的文本，如下所示：

• 代码块：

  from selenium import webdriver
  from selenium.webdriver.common.by import By
  from selenium.webdriver.support.ui import WebDriverWait
  from selenium.webdriver.support import expected_conditions as EC
  
  options = webdriver.ChromeOptions() 
  options.add_argument("start-maximized")
  options.add_argument('disable-infobars')
  driver=webdriver.Chrome(chrome_options=options, executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')
  driver.get('https://trends.google.com/trends/trendingsearches/realtime?geo=AR&category=all')
  titles = WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.XPATH, "//div[@class='title']")))
  for title in titles:
      print(title.text)
  driver.quit()
