I’m still playing around with the ‘irrelevant’ in an effort to stay ‘relevant’!

Back to the SEDI site for some more inspiration and this time to strip-out a listing of all (7,236) Canadian issuers listed here. You could bash-around here, working through the alphabet and numerals to get at the data; but there is a better way!

No need for Watir this time as I am able to bypass the javascript elements and use just Mechanize and Nokogiri Gems (v. addictive!) for a lightening-fast strip-and-parse from this otherwise ‘clunky’ site.

require 'nokogiri'
require 'mechanize'
require 'open-uri'

agent = Mechanize.new
ary_of_firms = Array.new
rows = Array.new

class Array 
 def to_cells(tag)
 self.map { |c| "<#{tag}>#{c}</#{tag}>" }.join
 end
end

file = File.open('./SEDI_Issuers.html'

 , "w")

[*('A'..'Z'),*('0'..'9')].each do |letter|

 page = agent.get('https://www.sedi.ca/sedi/SVTSelectSediIssuer?menukey=15.02.00&locale=en_CA')

sedi_form = page.form('form1')

 sedi_form.ISSUER_NAME = letter

 button = sedi_form.button_with(:value => "Search")

 page = agent.submit(sedi_form, button)

 doc = Nokogiri::HTML(page.body)

 i = 0

 table = doc.css('table')[9]

 #td:nth-child(3) font

 table.css('td:nth-child(3) font').each do |firm|
 if i > 0
 ary_of_firms << firm.text.strip
 end
 i+=1
 end

end

ary_of_firms.sort.uniq.each do |companies|
 puts companies
 rows << {"SEDI Issuer" => companies}
end

My last post scraping data of FINRA registrants for a particular Financial Institution got me thinking about getting a listing of all the firms that FINRA regulates.

FINRA does provide a site with a “listing” of all the firms they regulate

, but I wanted all the raw data for use in a spreadsheet (or where ever) and this was the challenge.

This was a great opportunity to use the Ruby Mechanize Gem alongside the Nokogiri Gem for parsing the output. Together these two Gems are very powerful and both crawl and mine data with beautiful efficiency

, grabbing the desired data and getting me my “true” list of all FINRA Members.

require 'nokogiri'
require 'mechanize'
require 'open-uri'

ary_of_members = Array.new
rows = Array.new
agent = Mechanize.new

file = File.open('./finra_members.html', "w")

page = agent.get('http://www.finra.org/AboutFINRA/MemberFirms/ListOfMembers/p012909')

doc = Nokogiri::HTML(page.body)

doc.css('.FNRW_Alphabetical_DL-result').each do |linkz|

page = agent.get('http://www.finra.org' + linkz['href'])
 doc = Nokogiri::HTML(page.body)

end
end

The task was to generate a listing of active FINRA registrants for a particular FI form FINRAs BrokerCheck website and once again some Ruby script with a Watir and Nokogiri Gem was the goto.
