我使用XPath来刮亚马逊网页特别,但它不工作。 任何一个可以给我一些建议吗? 这里的链接到该页面: 链接
我想刮这些:“有趣,信用卡大小的版画”我使用的代码是在这里:
from lxml import html
import requests
url = 'http://www.amazon.co.uk/dp/B009CX5VN2'
page = requests.get(url)
tree = html.fromstring(page.text)
feature_bullets = tree.xpath('//*[@id="feature-bullets"]/ul/li[1]/span/text()')
但feature_bullets总是空的。 真的需要一些帮助。
我下载的HTML不符合您的期望。 下面是对我的作品表达:
tree.xpath('//div[@id="technicalProductFeaturesATF"]/ul/li[1]/text()')
完整的程序:
from lxml import html
import requests
from pprint import pprint
url = 'http://www.amazon.co.uk/dp/B009CX5VN2'
page = requests.get(url)
tree = html.fromstring(page.text)
feature_bullets = tree.xpath('//div[@id="technicalProductFeaturesATF"]/ul/li/text()')
pprint(feature_bullets)
结果:
$ python foo.py
