=head1 NAME

WWW::Mechanize::Cookbook - Recipes for using WWW::Mechanize

=head1 INTRODUCTION

First, please note that many of these are possible just using
L<LWP::UserAgent>.  Since C<WWW::Mechanize> is a subclass of
L<LWP::UserAgent>, whatever works on C<LWP::UserAgent> should work
on C<WWW::Mechanize>.  See the L<lwpcook> man page included with
the L<libwww-perl> distribution.

=head1 BASICS

=head2 Launch the WWW::Mechanize browser

use WWW::Mechanize;

my $mech = WWW::Mechanize->new( autocheck => 1 );

The C<< 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.

=head2 Fetch a page

$mech->get( "http://search.cpan.org" );
    print $mech->content;

C<< $mech->content >> contains the raw HTML from the web page.  It
is not parsed or handled in any way, at least through the C<content>
method.

=head2 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" );

=head2 Fetch a password-protected page

Generally, just call C<credentials> before fetching the page.

$mech->credentials( 'admin' => 'password' );
    $mech->get( 'http://10.11.12.13/password.html' );
    print $mech->content();

=head1 LINKS

=head2 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 );

=head2 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 );

=head1 APPLICATIONS

=head2 Check all pages on a web site

Use Abe Timmerman's L<WWW::CheckSite>
L<http://search.cpan.org/dist/WWW-CheckSite/>
