需要帮助使用Selenium-Chromedriver和Python3，浏览器自动化

Question

我想把每个商家的名字打印在这一页上。我试过这个：

browser.get('https://www.trovaprezzi.it/televisori-lcd-plasma/prezzi-scheda-prodotto/lg_oled_cx3?sort=prezzo_totale')

Names = browser.find_elements_by_xpath("//span[@class='merchant_name']")

for span in Names:
    
print(span.text)

但是，当我运行代码时，它打印出一个巨大的空格，没有任何单词。

Answer 1

1您需要获取alt属性以获取卖家名称

2你需要使用等待。

3打印列表值时检查缩进。

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.wait import WebDriverWait


browser = webdriver.Chrome(executable_path='/snap/bin/chromium.chromedriver')

browser.get('https://www.trovaprezzi.it/televisori-lcd-plasma/prezzi-scheda-prodotto/lg_oled_cx3?sort=prezzo_totale')
wait = WebDriverWait(browser, 10)
wait.until(EC.visibility_of_all_elements_located((By.CSS_SELECTOR, ".merchant_name_and_logo img")))


names = browser.find_elements_by_css_selector(".merchant_name_and_logo img")

for span in names:
    print(span.get_attribute("alt"))

打印：

Climaconvenienza
Shopdigit
eBay
ePrice
Onlinestore
Shoppyssimo
Prezzo forte
eBay
eBay

Yeppon
Showprice
Galagross

Answer 2

请尝试在那里获取“span.text”属性，而不是值

Names = browser.find_elements_by_xpath("//span[@class='merchant_name']")

for span in Names:
    
    print(span..get_attribute("value"))

另外，不要忘记之前添加了一些等待/延迟

Names = browser.find_elements_by_xpath("//span[@class='merchant_name']")
