WWW::Mechanize::Cookbook - Recipes for using WWW::Mechanize
Introduction
First, please note that many of these are possible just using LWP::UserAgent. Since CWWWW::Mechanize is a subclass of LWP::UserAgent, whatever works on CWLWP::UserAgent should work on CWWWW::Mechanize. See the lwpcook man page included with the libwww-perl distribution.
Basics
Create a mech
use WWW::Mechanize;
my $mech = WWW::Mechanize->new( autocheck => 1 );
The CWautocheck => 1 tells Mechanize to die if any IO fails, so you don't have to manually check. It's easier that way. If you want to do your own error checking, leave it out.
Fetch a page
$mech->get( "http://search.cpan.org" );
print $mech->content;
CW$mech->content contains the raw HTML from the web page. It is not parsed or handled in any way, at least through the CWcontent method.
Fetch a page into a file
Sometimes you want to dump your results directly into a file. For example, there's no reason to read a JPEG into memory if you're only going to write it out immediately. This can also help with memory issues on large files.
$mech->get( "http://www.cpan.org/src/stable.tar.gz",
":content_file" => "stable.tar.gz" );
Links
Find all image links
Find all links that point to a JPEG, GIF or PNG.
my @links = $mech->find_all_links(
tag => "a", url_regex => qr/\.(jpe?g|gif|png)$/i );
Find all download links
Find all links that have the word download in them.
my @links = $mech->find_all_links(
tag => "a", text_regex => qr/\bdownload\b/i );
