Despite all the advancements in web APIs and interoperability, it's inevitable that, at some point in your career, you will have to "scrape" content from a website that was not built with web services in mind. And, despite its sometimes less-than-stellar reputation, web scraping is usually an entire legitimate activity-for example, to capture data from an old version of a website for insertion into a modern CMS. 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.
