Packt is pleased to announce the release of Instant Nokogiri, a hands-on guide to extracting information from the sources available on the Internet; sources that are not traditionally accessible to developers. This eBook is 52 pages long and is competitively priced at $11.04.

About the Author: Hunter Powers, a full stack web developer, began programming at the age of six, and has been gathering steam ever since. In 2011, Powers joined a big data streaming company. His work there has been represented by projects for AOL’s TechCrunch, Engadget, The Washington Post, The New York Times, Fox’s X-Factor, Fox Sports Australia, New York Presbyterian Hospital, and The NFL, to name but a few. Powers also directs, with credits for multiple commercials, web videos, and short films.

Nokogiri is an HTML, XML, SAX, and Reader parser. Among Nokogiri’s many features is the ability to search documents via XPath or CSS3 selectors. It parses and searches XML/HTML very quickly, and has also correctly implemented CSS3 selector support, as well as XPath support.

Instant Nokogiri provides step-by-step instructions on incorporating the power of the Nokogiri gem and data parsing into Ruby projects. Readers will learn the basics of designing a project around data parsing, exploring disparate data sources, and refining strategies and theories.

This eBook will teach users to combine their thoughts in a real-world, real-data sample application. Practical code samples will help readers examine common Nokogiri and Ruby methods that are useful in scraping and parsing. Packed with tips, tricks, code snippets, and expert advice; this handy guide will reveal the secrets behind effective caching, rate limiting, and masking identity.

This book is ideal for aspiring Ruby developers who are looking to incorporate screen scraping and parsing technology in their applications. Beginner level Ruby, basic HTML, and CSS experience is suggested.
