The Internet, with its profusion of information, has made us hungry for ever more, ever better data. Out of necessity, many of us have become pretty adept with search engine queries, but there are times when even the most powerful search engines aren't enough. If you've ever wanted your data in a different form than it's presented, or wanted to collect data from several sites and see it side-by-side without the constraints of a browser, then Spidering Hacks is for you. Spidering Hacks takes you to the next level in Internet data retrieval--beyond search engines--by showing you how to create spiders and bots to retrieve information from your favorite sites and data sources. You'll no longer feel constrained by the way host sites think you want to see their data presented--you'll learn how to scrape and repurpose raw data so you can view in a way that's meaningful to you. Written for developers, researchers, technical assistants, librarians, and power users, Spidering Hacks provides expert tips on spidering and scraping methodologies. You'll begin with a crash course in spidering concepts, tools (Perl, LWP, out-of-the-box utilities), and ethics (how to know when you've gone too far: what's acceptable and unacceptable). Next, you'll collect media files and data from databases. Then you'll learn how to interpret and understand the data, repurpose it for use in other applications, and even build authorized interfaces to integrate the data into your own content. By the time you finish Spidering Hacks, you'll be able to: Aggregate and associate data from disparate locations, then store and manipulate the data as you like Gain a competitive edge in business by knowing when competitors' products are on sale, and comparing sales ranks and product placement on e-commerce sites Integrate third-party data into your own applications or web sites Make your own site easier to scrape and more usable to others Keep up-to-date with your favorite comics strips, news stories, stock tips, and more without visiting the site every day Like the other books in O'Reilly's popular Hacks series, Spidering Hacks brings you 100 industrial-strength tips and tools from the experts to help you master this technology. If you're interested in data retrieval of any type, this book provides a wealth of data for finding a wealth of data.

淺入淺齣。比如“Auth, Cookie And Proxy”這章,這是寫爬蟲的三大基本功,本來是好材料,可惜作者沒有鋪開來說,三言兩語草草上菜。好材料,庸廚子。
評分還是用python吧,perl語法不習慣,不過這本書入門也不錯
評分這本書會擴展自己對 “爬蟲” 和 “數據抓取” 的認識,這本書中列齣瞭很多具體的實例,可以用來練手,提供數據抓取的練習。但覺得不是學習 “爬蟲” 的提高讀物
