by Sean M. Burke
EPUB
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 covers:
- Understanding LWP and its design
- Fetching and analyzing URLs
- Extracting information from HTML using regular expressions and tokens
- Working with the structure of HTML documents using trees
- Setting and inspecting HTTP headers and response codes
- Managing cookies
- Accessing information that requires authentication
- Extracting links
- Cooperating with proxy caches
- Writing web spiders (also known as robots) in a safe fashion
