BeautifulSoup 找不到标签

Question

我从一个网站中读取了一些 HTML，我试图将其解析为一个汤对象。之后，我提取了我查看过的 HTML 正文，发现它确实包含我正在寻找的项目。

我要查找的项目包含在<div> 标记内，带有class = 'listitem artikal obicniArtikal imaHover-disabled i index'.

现在我正在尝试做：

r = requests.get('https://www.olx.ba/pretraga?trazilica=golf+2', timeout=5)
soup = BeautifulSoup(r.text, 'html.parser') 
body = soup.find('div', attrs={'id':'rezultatipretrage'})

all_items = body.find_all('div', class_='listitem artikal obicniArtikal imaHover-disabled i index') 
print(all_items)

all_items 返回一个空列表，即使标签存在于body 中。

如果有人能告诉我发生了什么，我将不胜感激。

Answer 1

要选择包含所有指定类的标签，可以使用 BeautifulSoup 的select() 方法。

soup.select('div#rezultatipretrage div.listitem.artikal.obicniArtikal.imaHover-disabled.i.index') 将选择所有 <div> 类 listitem artikal obicniArtikal imaHover-disabled i index 标记在 <div> 标记下 id="rezultatipretrage":

from bs4 import BeautifulSoup
import requests

r = requests.get('https://www.olx.ba/pretraga?trazilica=golf+2', timeout=5)
soup = BeautifulSoup(r.text, 'lxml')

all_items = soup.select('div#rezultatipretrage div.listitem.artikal.obicniArtikal.imaHover-disabled.i.index')

for item in all_items:
    print(item.p.text)
    print('-' * 80)

将打印：
