使用python从html中提取数据

Question

我正在尝试从此代码中提取所有“a”标签中的文本，但出现错误：

（AttributeError: ResultSet 对象没有属性“find_all”。您可能将元素列表视为单个元素。当您打算调用 find() 时是否调用了 find_all()？）

我做错了什么？

import json
import time
from datetime import datetime
from discord import Webhook, RequestsWebhookAdapter
from discord_webhook import DiscordWebhook, DiscordEmbed
import discord
from bs4 import BeautifulSoup
from discord.ext import commands

r = requests.get("https://www.hypedc.com/nz/nike-air-force-1-07-black-black-cw2288-001")
soup = BeautifulSoup(r.content, 'lxml')
size = soup.find('div', id="size-selector-tab-mobile-0")
size = size.find_all('li', class_='col-xs-6 col-sm-8 col-md-6 col-lg-4')
size = size.find_all('a').text
print(size)

Answer 1

这里size.find_all('li', class_='col-xs-6 col-sm-8 col-md-6 col-lg-4')返回一个列表。因此，您需要对其进行迭代以获取大小。

import requests
r = requests.get("https://www.hypedc.com/nz/nike-air-force-1-07-black-black-cw2288-001")
soup = BeautifulSoup(r.content, 'lxml')
size = soup.find('div', id="size-selector-tab-mobile-0")

size = size.find_all('li') # return list

for t in size:
    print(t.a.text.strip())
