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.

Produktbeschreibung
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.

Rezensionen
"Spidering und Scraping? Ist das im Zeitalter von Web 2.0, RSS-Feeds und Webservices nicht so etwas von Web 1.0 (beta)? Braucht es dazu wirklich dieses Buch? [...] Ich fand es wichtig, spannend (ja, wirklich) und informativ. [...] Erst einmal führt es [...] in die Grundlagen ein und erinnert ausführlich daran, daß wir unseren Spidern 'Gutes Benehmen' beizubringen haben, wozu die Beachtung der robots.txt ebenso gehört, wie die Verpflichtung, den zu spidernden Server durch allzuhäufige Nachfragen nicht lahmzulegen. Und sauber identifizierbar sollte unser Spider ebenfalls sein. Danach geht es in medias res. Es wird eine (Perl-) Toolbox zusammengestellt, die uns das Spidern und Scrapen erleichtert. Aber auch auf andere Unix-Werkzeuge, wie z.B. wget oder lynx wird eingegangen. Und dann wird es erst recht interessant: Es werden Beispiele vorgeführt, wie man mit einfachen Mitteln Mashups baut [..]. Die Beispiele sind fast alle in Perl, vollständig dokumentiert und die Erklärungen sind witzig geschrieben und in einem Englisch, das auch ich sicher lesen kann. Um also auf die Eingangsfrage zurückzukommen: Ja, man braucht so ein Buch und wenn es so ein gut geschriebenes Buch ist wie Spidering Hacks, um so besser." - Schockwellenreiter.de, Juli 2006 Lesen Sie die ausführliche Rezension unter: http://www.schockwellenreiter.de/2006/07/26.html#ichHabeGelesenSpideringHacks
