Book Description
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

Book Description
Is Ajax a new technology, or the same old stuff web developers have been using for years? Both, actually. This book demonstrates not only how tried-and-true web standards make Ajax possible, but how these older technologies allow you to give sites a decidedly modern Web 2.0 feel. Ajax: The Definitive Guide explains how to use standards like JavaScript, XML, CSS, and XHTML, along with the XMLHttpRequest object, to build browser-based web applications that function like desktop programs. You get a complete background on what goes into today's web sites and applications, and learn to leverage these tools along with Ajax for advanced browser searching, web services, mashups, and more. You discover how to turn a web browser and web site into a true application, and why developing with Ajax is faster, easier and cheaper. The book also explains: How to connect server-side backend components to user interfaces in the browser Loading and manipulating XML documents, and how to replace XML with JSON Manipulating the Document Object Model (DOM) Designing Ajax interfaces for usability, functionality, visualization, and accessibility Site navigation layout, including issues with Ajax and the browser's back button Adding life to tables & lists, navigation boxes and windows Animation creation, interactive forms, and data validation Search, web services and mash-ups Applying Ajax to business communications, and creating Internet games without plug-ins The advantages of modular coding, ways to optimize Ajax applications, and more This book also provides references to XML and XSLT, popular JavaScript Frameworks, Libraries, and Toolkits, and various Web Service APIs. By offering web developers a much broader set of tools and options, Ajax gives developers a new way to create content on the Web, while throwing off the constraints of the past. Ajax: The Definitive Guide describes the contents of this unique toolbox in exhaustive detail, and explains how to get the most out of it.
