vue根据下标获取数组中的值_document.getElementBy

from lxml import etree
import requests
url = 'https://www.pearvideo.com/'  # 首页地址
data = { 

}
headers = { 
"User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) "

}
session = requests.Session()
page_one = session.get(url, headers=headers).text
# page_one.encoding = 'utf-8'
print('-------首页请求成功--------')
tree = etree.HTML(page_one)
page_list = tree.xpath('//*[@id="navbar"]/ul/li')
for li in page_list:
# todo 方法1
page_list_li = li.xpath('./a/@href')  # @href采用定位的方式 找到需要的key对应的值
print(li[0].text)  # 直接获取li下面的文本
print(li[0].tag)  #获取<a>标签名a
print(li[0].attrib)  # 获取<a>标签的属性href和class值
# todo 方法2
for li_2 in range(len(li)):  # todo 从上一个li标签中获取到我要的信息。参考：https://www.jb51.net/article/132145.htm
print(li[li_2].tag)  #获取<a>标签名a
print(li[li_2].attrib)  # 获取<a>标签的属性href和class
print(li[li_2].text)  # 获取到li下面的文本
