This book, written by scraping expert Matthew Turland, covers web scraping techniques and topics that range from the simple to exotic using a variety of technologies and frameworks: . Understanding HTTP requests . The PHP HTTP streams wrapper . cURL . pecl_http . PEAR: HTTP . Zend_Http_Client . Building your own scraping library . Using Tidy . Analyzing code with the DOM, SimpleXML and XMLReader extensions . CSS selector libraries . PCRE pattern matching . Tips and Tricks . Multiprocessing / parallel processing

Book Description
This book provides a complete and modern guide to web scraping, using Python as the programming language, without glossing over important details or best practices. Written with a data science audience in mind, the book explores both scraping and the larger context of web technologies in which it operates, to ensure full understanding. The authors recommend web scraping as a powerful tool for any data scientist’s arsenal, as many data science projects start by obtaining an appropriate data set. Starting with a brief overview on scraping and real-life use cases, the authors explore the core concepts of HTTP, HTML, and CSS to provide a solid foundation. Along with a quick Python primer, they cover Selenium for JavaScript-heavy sites, and web crawling in detail. The book finishes with a recap of best practices and a collection of examples that bring together everything you've learned and illustrate various data science use cases.
