VERSION
version 1.86
INTRODUCTION
First, please note that many of these are possible just using
LWP::UserAgent. Since "WWW::Mechanize" is a subclass of
LWP::UserAgent, whatever works on "LWP::UserAgent" should work on
"WWW::Mechanize". See the lwpcook man page included with the libwww-
perl distribution.
BASICS
Launch the WWW::Mechanize browser
use WWW::Mechanize;
my $mech = WWW::Mechanize->new( autocheck => 1 );
The "autocheck => 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 $mech->content;
"$mech->content" contains the raw HTML from the web page. It is not
parsed or handled in any way, at least through the "content" 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" );
Fetch a password-protected page
Generally, just call "credentials" before fetching the page.
$mech->credentials( 'admin' => 'password' );
$mech->get( 'http://10.11.12.13/password.html' );
print $mech->content();
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 );
ADVANCED
See what will be sent without actually sending anything
$mech->add_handler("request_send", sub { shift->dump; exit; });
$mech->get("http://www.example.com");
