import requests
import re
from bs4 import BeautifulSoup
from lxml import etree
from selenium import webdriver
url = 'http://www.ok226.com'
r = requests.get(url)
r.encoding = 'gb2312'
# 利用 re
matchs = re.findall(r"(?<=href=\").+?(?=\")|(?<=href=\').+?(?=\')" , r.text)
for link in matchs:
print(link)
print()
# 利用 BeautifulSoup4 (DOM树)
soup = BeautifulSoup(r.text,'lxml')
for a in soup.find_all('a'):
link = a['href']
print(link)
print()
# 利用 lxml.etree (XPath)
tree = etree.HTML(r.text)
for link in tree.xpath("//@href"):
print(link)
print()
# 利用selenium(要开浏览器!)
driver = webdriver.Firefox()
driver.get(url)
for link in driver.find_elements_by_tag_name("a"):
print(link.get_attribute("href"))
driver.close()
