( #3333=superdoc: print w/replies, xml ) Need Help??

I am interested in writing a perl script that goes to the following link and extracts the number 1975:

That website is the amount of white men born in the year 1923 who live in San Diego County, California in 1940. I am trying to do this in a loop structure to generalize over multiple counties and birth years.

I have installed WWW::Mechanize::Firefox.

Here is some code that I have written. I make to the forms section and then I'm completely confused as to what to do. :(

use strict; use warnings; use WWW::Mechanize::Firefox; my $mech = WWW::Mechanize::Firefox->new( activate => 1, # bring the tab to the foreground ); $mech->get(' +0&query=%2Bevent_place_level_1%3ACalifornia%20%2Bevent_place_level_2% +3A%22San%20Diego%22%20%2Bbirth_year%3A1923-1923~%20%2Bgender%3AM%20%2 +Brace%3AWhite&collection_id=2000219',':content_file' => 'main.html', +synchronize => 0); my $retries = 10; while ($retries-- and $mech->is_visible( xpath => '//*[@id="hourgl +ass"]' )) { print "Sleep until we find the thing\n"; sleep 2; }; die "Timeout while waiting for application" if 0 > $retries; # Now the hourglass is not visible anymore #fill out the search form my @forms = $mech->forms(); #<input id="census_bp" name="birth_place" type="text" tabindex="0"/> + #A selector prefixed with '#' must match the id attribute of the input +. A selector prefixed with '.' matches the class attribute. A selecto +r prefixed with '^' or with no prefix matches the name attribute. $mech->field( birth_place => 'value_for_birth_place' ); # Click on the submit $mech->click({xpath => '//*[@class="form-submit"]'});
Would appreciate any help in getting it to work!
