我得到了myi搜索的打印列表你可以看到终端打印列表中有myip，所以它应该与我的if条件匹配，它会被点击，所以我应该在谷歌上搜索myip，不知怎么的我没有得到它还有我打印了很长的列表，这里是1，但我认为不应该是，你可以看到我得到10个搜索结果，所以应该是10个

使用

chrome - 103.0.5060.134
chromewebdriver - 103.0.5060.134
python- 3.10.5
selenium - 4.3.0

Answer 1

我看到你的XPATH是错误的，你目前正在做的是在你的页面中获取所有的ul标签。然而，您在这里真正需要做的是获取所有li元素，因为您所有的自动完成建议都存储在li中。

虽然您的XPATH字符串可以进行优化，但我会通过简单的更改来保持它的原样。

optionsList = driver.find_elements(By.XPATH,"//body/div[@class='L3eUgb']//form[@role='search']//div[@class='A8SBwf emcav']//div[@class='mkHrUc']/ul[1]/div[@role='presentation']/ul[@role='listbox']/li")

现在应该可以了。

Answer 2

您。。可能不需要很长的xpath来获取这些元素。这里有一个(稍微(更强大的解决方案，如果出现cookie按钮，它将取消cookie按钮，等待元素加载，搜索字符串，浏览结果并单击相关的：

from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.action_chains import ActionChains
chrome_options = Options()
chrome_options.add_argument("--no-sandbox")

webdriver_service = Service("chromedriver/chromedriver") ## path to where you saved chromedriver binary
browser = webdriver.Chrome(service=webdriver_service, options=chrome_options)
url = 'https://www.google.com'
browser.get(url)
try:
deny_cookies = WebDriverWait(browser, 20).until(EC.element_to_be_clickable((By.XPATH, "//button[@id='W0wltc']")))
deny_cookies.click()
except Exception as e:
print('no cookies')
search_box = WebDriverWait(browser, 20).until(EC.element_to_be_clickable((By.XPATH, "//input[@name='q']")))
search_box.send_keys('myi')
search_box.click()
options = WebDriverWait(browser, 30).until(EC.presence_of_all_elements_located((By.XPATH, "//li[@data-view-type='1']")))
for option in options:
print(option.text)
if option.text == 'myip':
option.click()
break

selenium/chrome设置是针对linux的，但是相关部分是：

• 导入：WebDriverWait，expected_conditions，By
• browser.get(url(之后的部分，在这里我们明确地等待元素加载并可点击
