Hi Monks,

I'm a perl beginner and am learning to use the www::mechanize module to get a list of genome sequencing projects from http://www.ncbi.nlm.nih.gov/Traces/wgs/. After I fill in the form, I cannot figure out how to select 'All' from the 'Show projects on page' listbox.

I tried 'find_all_inputs' with 'select' as criteria for a listbox, but nothing gets assigned to the variable. My other issue is not being able to click on the 'Download as TAB delimited list' link to output results to file.

I can complete this task using the browser, but then I don't learn. Below are the few lines of code I have so far. Your advice will be a great help.

many thanks! 

#!/usr/local/bin/perl
use strict;
use warnings;
use autodie qw/ open close /;
use 5.012;
use WWW::Mechanize;

# create WWW::Mechanize object
# autocheck 1 checks each request to ensure it was successful
my $browser = WWW::Mechanize->new( autocheck => [1] );

# retrieve page
$browser->get( 'http://www.ncbi.nlm.nih.gov/Traces/wgs/' );

#select form to fill based on mech-dump output
$browser->form_number(1); 
# fill field 'term' with name of species
$browser->field( 'term', 'Escherichia' );

# click apply button
$browser->submit( 'Apply' );

my $url = $browser->uri;
# launch browser to test url
#system( 'firefox', $url );

my @inputs = $browser->find_all_inputs(
    type => 'select'
);
say @inputs;
