lxml解析网页速度比BeautifulSoup快 lxml解析网页速度比BeautifulSou

我的代码：

# -*- coding: utf-8 -*- import requests from time import ctime from lxml import etree from bs4 import BeautifulSoupurl = 'http://www.cnblogs.com/descusr/archive/2012/06/20/2557075.html' tries = 300 web_data = https://www.it610.com/article/requests.get(url).text# step 1 print('lxml start at:', ctime()) while tries > 0: lxml_page = etree.HTML(web_data) tries = tries - 1 print('lxml done at:', ctime())# step 2 print('soup start at:', ctime()) while tries > 0: soup_page = BeautifulSoup(web_data, 'lxml') tries = tries - 1 print('soup done at:', ctime())

我是分步运行的：先注释掉step2，运行step1；之后注释掉1，运行2。新手轻拍
运行结果： 【lxml解析网页速度比BeautifulSoup快】解析一个博客页面300次，Beautiful用了约8秒，lxml用了约1秒
