【问题描述】：

import time
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC


PATH = "C:\Program Files (x86)\chromedriver.exe"
driver = webdriver.Chrome(PATH)

driver.get('https://soundcloud.com/jujubucks')
print(driver.title)

search = driver.find_element_by_tag_name('span class=""')
print(search.text)

driver.quit()

我尝试按类和标签名称查找此元素。它只是返回一个错误。是否可以抓取此类中的数据？

这是它返回的错误

【问题讨论】：

• 当我得到那个页面时，根本没有<span> 标签。你在哪里看到<span>？
• 打开

  并转到

  然后右键单击

  然后选择edit as html和所有特定于span 类所在的歌曲。
• span 是标签名； span class="" 不是。对不是标签名称的东西调用 find_element_by_tag_name() 是没有意义的。
• 这不是您的代码显示的内容。
