The realization method of Python climbing the kingdoms of the _python

The crawler tutorial in this article is divided into four parts:

1. Where do I climb from?

2. What what to climb

3. How to Crawl

4. How the information saves save after crawling

One, from where to climb

Three kingdoms

Two, climb what

The full text of the kingdoms

Third, how to climb

When you open F12 on the Chrome page, you can find the content of the article in the node

<div id= "Con" class= "Bookyuanjiao" >

Just find this node and write the content to an HTML file.

Content = Soup.find ("div", {"Class": "Bookyuanjiao", "id": "Con"})

Four, how to save after the climb

The main thing is to get the content, splicing to an HTML file, and then save it.

#!usr/bin/env #-*-coding:utf-8-*-import urllib2 import os from BS4 import beautifulsoup as BS import locale import sy s from lxml import etree import re reload (SYS) sys.setdefaultencoding (' GBK ') Sub_folder = Os.path.join (OS.GETCWD (), "San Guoyanyi ") If not os.path.exists (Sub_folder): Os.mkdir (sub_folder) path = sub_folder # Customize HTML as head of the A Rticles input = open (R ' 0.html ', ' r ') head = input.read () domain = ' http://www.shicimingju.com/book/sanguoyanyi.html ' t = Domain.find (R '. html ') New_domain = '/'. Join (Domain.split ("/") [: -2]) First_chapter_url = Domain[:t] + "/" + str (1) + '. html ' Print First_chapter_url # Get URL if chapter lists req = Urllib2.  Request (url=domain) resp = urllib2.urlopen (req) HTML = resp.read () soup = BS (html, ' lxml ') chapter_list = Soup.find ("div",
{"Class": "Bookyuanjiao", "id": "Mulu"}) sel = etree. HTML (str (chapter_list)) result = Sel.xpath ('//li/a/@href ') for each_link in Result:each_chapter_link = New_domain + "/ "+ Each_link Print eaCh_chapter_link req = urllib2. Request (url=each_chapter_link) resp = urllib2.urlopen (req) HTML = resp.read () soup = BS (html, ' lxml ') content = S Oup.find ("div", {"Class": "Bookyuanjiao", "id": "Con"}) title = Soup.title.text title = Title.split (U ' _ "The Kingdoms" _ poetry) [
  0] html = str (content) HTML = head + HTML + "</body> 

The contents of 0.html are as follows

Summarize

The above is to use Python to crawl the realization of the kingdoms of the way, I hope to learn Python can help, if there are questions you can message exchange.
