老司机带你如何定位span元素中的文本--Selenium
页面结构网易登入页

#我们对网页的操作没有报错不代表自动化没有问题
#此时需要通过页面返回的信息做一个判断，来做人工的定位

from selenium import webdriver
from selenium.webdriver.common.by import By
import time
driver = webdriver.Chrome()
driver.get("https://www.126.com/")
time.sleep(4)
print('Before login............')
title = driver.title
print(title)
nowURL = driver.current_url
print(nowURL)
#这是为了先却换到运行模块，不然会定位不到元素
fname =driver.find_element(By.XPATH,'/html/body/div/div/div/div/div/div/div/iframe')
driver.switch_to.frame(fname)
#百度输入框输入内容
driver.find_element(By.XPATH,"//input[@name='email']").clear()
driver.find_element(By.XPATH,"//input[@name='email']").send_keys("username")
driver.find_element(By.NAME,"password").clear()
driver.find_element(By.NAME,"password").send_keys("password")
driver.find_element(By.ID,"dologin").click()
#driver.find_element(By.CSS_SELECTOR,"")
time.sleep(5)
print('After login............')
title = driver.title
print(title)
nowURL = driver.current_url
print(nowURL)
#此种方法不能点出text
# user = driver.find_elements(By.ID,'spnUid')
#后面的这3种方法都可以取登入页面后用户账号信息来验证自动化是否正常
# user =driver.find_element(By.XPATH,'//*[@id="spnUid"]').text
# user =driver.find_element(By.XPATH,'/html/body/header/div/ul/li/a//*[@id="spnUid"]').text
user =driver.find_element(By.CSS_SELECTOR,"").text
print(user)
driver.quit()</font>异常
打印结果找不到text。
解决办法
通过疯狂百度，尝试了text，getAttribute通通失败。一位热心网友的回复救了我，他怀疑是元素定位不准确导致的。于是我只定位了第一个元素，.text获取成功。
<font size="3">
user =driver.find_element(By.XPATH,'/html/body/header/div/ul/li/a//*[@id="spnUid"]').text</font>
