Question

我正在努力拉扯“＃id;＆＃39;或者＆＃39;数据值＆＃39;从这个html块中分配出来并将它们分配给列表。我似乎没有指定正确的目标。我哪里错了？最后我想在is_in_stock部分中定位单个产品ID。

我的代码 -

import requests
from bs4 import BeautifulSoup as bs

response = session.get(product_url)
soup = bs(response.text,'lxml')
div = soup.find("div",{"class":"item"})
all_sizes = div.find_all("data")

HTML-

Answer 1

这应该适合你。

c(apply(x, 1, c))
# [1] 1 3 3 6 5 7 6 4 7 8

Answer 2

您已走上正轨，但您需要tag.find_all而不是find：

ids = []
for div in soup.find_all("div", {"class":"attribute-item"}):
    ids.append(x['data-value'])

Python：获取＆＃34; id＆＃34;或＆＃34;数据值＆＃34;来自HTML？
