如何使用Selenium Python从duckduckgo的搜索结果中提取文本 [英] How to extract the text from the search results of duckduckgo using Selenium Python

问题描述

我正在尝试使用以下方法获取搜索结果中的鸭子的链接描述:

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)

我收到错误列表"对象没有属性文本".我能够使用类似的方法来获取搜索结果标题，但由于某种原因，我无法从这个特定的 xpath 中提取文本.

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.

推荐答案

要从 DuckDuckGo 中提取搜索结果的链接描述，您必须为 WebDriverWait 引入 WebDriverWaitem>所有元素的可见性，您可以使用以下解决方案:

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:

• 代码块:

• 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()
