python - Dryscrape：使用 xpath 从父节点列表中刮取子节点数据

Question

我试图使用 dryscrape 和 python来抓取http://quotes.toscrape.com/用于学习目的。我能够使用 class="quote" 获得所有 div。想循环使用 class="quote" 的 div 列表，并使用 xpath 从此父元素获取多个数据。

import dryscrape
from bs4 import BeautifulSoup
session = dryscrape.Session()
url = 'http://quotes.toscrape.com/'
print 'Visiting the URL...'
session.visit(url)
print 'Status: ', session.status_code()
for div in session.xpath("//div[@class='quote']"):
    # please help me to scrape author and quote for each div elements

Answer 1

import requests
from bs4 import BeautifulSoup
url = 'http://quotes.toscrape.com/'
r = requests.get(url)
soup = BeautifulSoup(r.text)
for div in soup.findAll("div", {"class": "quote"}):
  print('Quote : ' + div.find('span').get_text())
  print('Author : ' + div.find('small').get_text())

Answer 2

我们可以遍历每个 xpath 元素，这些元素将是具有单个元素内容的对象。每个对象都有获取数据的方法。

import dryscrape
session = dryscrape.Session()
url = 'http://quotes.toscrape.com/'
print 'Visiting the URL...'
session.visit(url)
print 'Status: ', session.status_code()
for div in session.xpath("//div[@class='quote']"):
    print "Quote: ", div.at_xpath(".//span").text()
    print "Author: ", div.at_xpath(".//small").text()
