解析銀行對賬單並返回二維數組的值

Question

我試圖解析我的在線銀行對賬單，檢索值，然後獲取單個值。這是一個示例語句。 otherrefcode代表我發送的款項，refcode代表我收到的款項。

Date  Description Type [?] In (£) Out (£) Balance (£) 
29 Aug 13 person1 otherrefcode 29AUG13 18:23 FPO  42.81 662.68 
29 Aug 13 person2 otherrefcode 29AUG13 18:21 FPO  599.91 705.49 
29 Aug 13 person3 refcode  TFR  30.80 1,305.40 
28 Aug 13 person4 otherrefcode 28AUG13 14:23 FPO  25.27 1,336.20 
28 Aug 13 person5 refcode  TFR  41.08 1,361.47 

這是我的紅寶石代碼。我如何獲取個人價值？

require 'watir-webdriver' 
require 'nokogiri' 

def toprice(data) 
    data.to_s.match(/\d\d\.\d\d/).to_s 
end 

$browser = Watir::Browser.new :firefox 
$browser.goto("bankurl") 
$page_html = Nokogiri::HTML.parse($browser.html) 

table_array = Array.new 
table = $browser.table(:class,'statement smartRewardsOffers') 
table.rows.each do |row| 
    row_array = Array.new 
    row.cells.each do |cell| 
     row_array << cell.text 
    end 
    table_array << row_array 
end 
puts "1strun" 
puts table_array[1..4][1] 
puts "2ndrun" 
puts table_array[1][1..4] 

輸出

1strun 
person1 otherrefcode 29AUG13 18:23 
FPO 

42.81 
2ndrun 
29 Aug 13 
person2 otherrefcode 29AUG13 18:21 
FPO 

599.91 
705.49

Answer 1

你已經得到的文本每個細胞進入table_array。你只需要得到正確的細胞。它是一個2D數組，所以第一個索引是行，第二個索引是列。請注意，該數組是基於0的索引（即0代表第一行/列）。

# type in the first row 
puts table_array[1][2] 
#=> "FPO" 

# person in the first row 
puts table_array[1][1].split[0] 
#=> "person2" 

# out value in the second row 
puts table_array[2][4] 
#=> "599.91" 

與這些痕跡的工作是不是很好。同樣，在這一點上，描述欄的分割更加困難。相反，我會建議爲每一行創建一個散列。

table_array = Array.new 
table_rows = $browser.table(:class,'statement smartRewardsOffers') 
table_rows.rows.to_a[1..-1].each do |row| 
    row_hash = Hash.new 
    row_hash[:date] = row.cell(:index => 0).text 
    row_hash[:person] = row.cell(:index => 1).span(:index => 0).text 
    row_hash[:code] = row.cell(:index => 1).span(:index => 2).text rescue '' 
    row_hash[:time] = row.cell(:index => 1).span(:index => 4).text rescue '' 
    row_hash[:type] = row.cell(:index => 2).text 
    row_hash[:in] = row.cell(:index => 3).text 
    row_hash[:out] = row.cell(:index => 4).text 
    row_hash[:balance] = row.cell(:index => 5).text 
    table_array << row_hash 
end 

# First data row's information 
row = 0 # Note that the rows are 0-based index 
puts table_array[row][:date] #=> "29 Aug 13" 
puts table_array[row][:person] #=> "person1" 
puts table_array[row][:code] #=> "ref" 
puts table_array[row][:time] #=> "29AUG13 18:23" 
puts table_array[row][:type] #=> "FPO" 
puts table_array[row][:in] #=> "" 
puts table_array[row][:out] #=> "42.81" 
puts table_array[row][:balance] #=> "662.68"
