Perl & LWP
Autor Sean M. Burkeen Limba Engleză Paperback – 2 iul 2002
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 designFetching and analyzing URLsExtracting information from HTML using regular expressions and tokensWorking with the structure of HTML documents using treesSetting and inspecting HTTP headers and response codesManaging cookiesAccessing information that requires authenticationExtracting linksCooperating with proxy cachesWriting web spiders (also known as robots) in a safe fashion
