How to extract the text from the search results of duckduckgo using Selenium Python

问题

I am trying to get the link descriptions of duckduck of search results using the following:

results=browser.find_elements_by_xpath("//div[@id='links']/div/div/div[2]")
description=[]
for result in results:
  description.append(result.text)

I am getting the error 'list' object has no attribute 'text'. I was able to use a similar method to get the search result titles, but for some reason I am unable to extract the text from this particular xpath.

To extract the link descriptions of the search results from DuckDuckGo you have to induce WebDriverWait for the visibility of all elements located and you can use the following solution:

• Code Block:

  from selenium import webdriver
  from selenium.webdriver.support.ui import WebDriverWait
  from selenium.webdriver.support import expected_conditions as EC
  from selenium.webdriver.common.by import By
  
  options = webdriver.ChromeOptions()
  options.add_argument("start-maximized")
  options.add_argument("disable-infobars")
  options.add_argument("--disable-extensions")
  driver = webdriver.Chrome(chrome_options=options, executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')
  driver.get('https://duckduckgo.com/')
  search_box = WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.NAME, "q")))
  search_box.send_keys("Selenium")
  search_box.submit()
  elements = WebDriverWait(driver, 10).until(EC.visibility_of_all_elements_located((By.XPATH, "//div[@id='links']/div/div/div[2]")))
  for ele in elements:
      print(ele.text)
  driver.quit()

  Introduction. Selenium is a trace element that is naturally present in many foods, added to others, and available as a dietary supplement.

You don't have to create a for loop for the empty list... try using this code:

results=driver.find_elements_by_xpath("//div[@id='links']/div/div/div[2]")

description=[]

for result in results:
    description.append(result.text)

Example: To test this I simply typed 'hmm' in DuckDuckGo so the URL is https://duckduckgo.com/?q=hmm&t=h_&ia=web

from selenium import webdriver

driver=webdriver.Chrome()
driver.get('https://duckduckgo.com/?q=hmm&t=h_&ia=web')

results=driver.find_elements_by_xpath("//div[@id='links']/div/div/div[2]")

description=[]

for result in results:
    description.append(result.text)

print(description[0])
print(' ')
print(description[1])
print(' ')
print(description[2])

Output:
