我是硒的新手 . 我想从网站的以下HTML代码中提取HTML表格中的链接文本 .
代码片段：
<div style="width:210px" id="calenderdiv">
<table id="calender" align="center" bgcolor="#ABABAB" width="90%" cellspacing="1" cellpadding="0" border="0">

对于上面的代码片段，我在selenium中编写了以下代码：
from selenium import webdriver
from selenium.webdriver.common.by import By
option = webdriver.ChromeOptions()
option.add_argument("--incognito")
option.add_argument("--start-maximized")
chrome_path = r"C:\Users\singh\Downloads\chromedriver_win32\chromedriver.exe"
browser = webdriver.Chrome(chrome_path, options=option)
browser.get("https://timesofindia.indiatimes.com/archive/year-2010,month-1.cms")
browser.implicitly_wait(10)
num = []
numbers = browser.find_elements(By.XPATH, "//table[@class = 'calender']/tbody/tr/td/a[@href]")
for n in numbers:
number = n.text
num.append(number)
预期产出：
num = ['S', 'M', 'T', 'W', 'T', 'F', 'S', '1', '2', '3', '4', '5', '6', '7', '8', '9', '10', '11', '12', '13', '14', '15', '16', '17', '18', '19', '20', '21', '22', '23', '24', '25', '26', '27', '28', '29', '30', '31']
该程序将num和numbers列表作为空列表返回 .
我知道代码中输入的XPath中的某些内容不正确 . 但我无法弄清楚错误是什么 .

有两个问题
calender是id，而不是class .2.要获得
href，您需要使用get_attribute，而不是文本
