如何在美丽的汤中从桌子上提取标签

Question

这是我的漂亮汤代码。

  topics_url = 'https://www.goodreads.com/review/list/47437459?page=1&ref=nav_mybooks'
  response = requests.get(topics_url)
  page_content = response.text
  doc = BeautifulSoup(page_content, 'html.parser')
  table_title = doc.find_all('td', {'class' : 'field title'})
  table_title[:5]

输出

​

得到td后，我想访问'a‘标签，并从'a’标签中提取标题。由于没有类或id，我如何从'a‘标签中获得标题？

愿望输出：

两个城市的故事

智人:人类简史

还有所有..。

Answer 1

它们是title的属性值。所以您可以调用.get('title')来获取该数据点。

import requests
from bs4 import BeautifulSoup

topics_url = 'https://www.goodreads.com/review/list/47437459?page=1&ref=nav_mybooks'
response = requests.get(topics_url)
page_content = response.text
doc = BeautifulSoup(page_content, 'html.parser')
for table_title in doc.select('#books tbody tr'):
  t= table_title.select_one('td.field.title div a').get('title')
  print(t)

输出：
