How to return a list of all email addresses associated with a company using the basecamp API

Question

I've managed to get this to almost work but I think I'm getting something seriously confused. All the examples seem to cover finding single records based on their id.

I thought I would be able to pass a param to filter on a single attribute

https://xxxx.basecamphq.com/companies.xml?name=xxxx

Basecamp::Company.find(:all, :params => { :name => xxx })

require 'rubygems'
require 'English'
require 'trollop'
require 'basecamp'
require 'ap'

opts = Trollop::options do
    version "1.0"
    banner <<-EOS
    #{File.basename($0)}
    Description: Dump the users from a company stored in basecampe via the api.

    Usage:
           #{File.basename($0)} [options]
    where [options] are:
    EOS
    opt :company , "Company to export" , :default => "XXXX"
    opt :token_file, "File to read token from " , :default => "~/.basecamp/token"
end


basecamp_token = IO.read(File.expand_path(opts[:token_file])).chomp

Basecamp.establish_connection!('xxxx.basecamphq.com', basecamp_token , 'X' , true)

#Work out company id from company name
company = Basecamp::Company.find(:all).select { |c| c.attributes["name"] == opts[:company] }
company_id = company[0].instance_variable_get("@attributes")["id"]

people = Basecamp::Person.find(:all, :params => {:company_id => company_id })
#ap people

#todo work out how to iterate over all people
puts people[0].instance_variable_get("@attributes")["email_address"]

Turns out :first will return me a single company as I wanted, however I don't find the method the logical as I don't want the first entry, I want any entry that matches my params..

#Work out company id from company name
company = Basecamp::Company.find(:first, :params => {:name => opts[:company] })
people = Basecamp::Person.find(:all, :params => {:company_id => company.id })

people.each do | person |
    puts person.email_address
end
