The LWP (Library for WWW in Perl) suite of modules lets your programs download and extract information from the Web. Perl & LWP shows how to make web requests, submit forms, and even provide authentication information, and it demonstrates using regular expressions, tokens, and trees to parse HTML.. This book is a must have for Perl programmers who want to automate and mine the Web.
product description

Perl soared to popularity as a language for creating and managing web content, but with LWP (Library for WWW in Perl), Perl is equally adept at consuming information on the Web. LWP is a suite of modules for fetching and processing web pages.

The Web is a vast data source that contains everything from stock prices to movie credits, and with LWP all that data is just a few lines of code away. Anything you do on the Web, whether it\'s buying or selling, reading or writing, uploading or downloading, news to e-commerce, can be controlled with Perl and LWP. You can automate Web-based purchase orders as easily as you can set up a program to download MP3 files from a web site.

Perl & LWP includes many step-by-step examples that show how to apply the various techniques. Programs to extract information from the web sites of BBC News, Altavista, ABEBooks.com, and the Weather Underground, to name just a few, are explained in detail, so that you understand how and why they work.

Perl programmers who want to automate and mine the web can pick up this book and be immediately productive. Written by a contributor to LWP, and with a foreword by one of LWP\'s creators, Perl & LWP is the authoritative guide to this powerful and popular toolkit.
