Title: Rich samples, fit your specific needs if you're Perl lover
Review: If you are a Perl lover and looking for a book to help you extracting contents from this huge resourceful Internet, this book quite fits your needs. Overall is good, the author shows you how to setup your spidering tools -- Perl modules. Yes, Perl, if you're Java folks, too bad. He shows you how to use Perl modules on crawling web pages, logging on to systems, extracting specific contents, and massaging data to your needs, across 100 different scenarios. Most of them are practical, but they don't cover much of the details, you have to read the programs listed in the book, which is quite painful for non-Perl people like me. In addition, it doesn't provide much of resulting screen shots after running the sample codes. Most importantly, the author tries to avoid the copyright questions by delegating URL links for readers to reference. In general, it's still a good tool book in spidering field.
