Question

我正在尝试解析我的在线银行对帐单，检索这些值，然后获取各个值。这是一个示例声明。 otherrefcode代表我发送的款项，refcode代表我收到的款项。

  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

这是我的红宝石代码。如何获取单个值？

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]

输出

1strun
person1 otherrefcode 29AUG13 18:23
FPO

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

599.91
705.49

声明的HTML（好吧，前3个交易 - 警告，76行长。）

您已将每个单元格的文本输入table_array。你只需要获得正确的细胞。它是一个2D数组，因此第一个索引是行，第二个索引是列。请注意，该数组是从0开始的索引（即0表示第一行/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"

使用这些指标并不是那么好。同样，此时拆分描述列更加困难。相反，我建议为每一行创建一个哈希值。

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"
