ruby - 解析具有不同分隔符的文本 - 带分组

Question

我正在编辑我之前的帖子，因为我取得了一些进展，但现在有点卡住了:

文本文件示例如下。我现在可以读取文件并进行一些解析以获取我需要的数据并输出文件。但是，输出将数据放在不同的行上，我需要将输出文件(名称、到期日期、last_used、address1、address2、city、state、zip)放在以逗号分隔的一行上。

到目前为止的代码如下:

def is_numeric?(object)
true if Float(object) rescue false
end



def load_file
raw_records = []
infile = File.open("testfile.txt", "r") 
#counter =1 

while line = infile.gets
possible_account_number = line[0,16]
if is_numeric?(possible_account_number)
  account_number= possible_account_number[5,11]
  name = line[21,27].strip.gsub(/\,/,"")
  expire_date = line[108,8].strip
  last_used = line[117,8].strip    
  line = infile.gets
  line = infile.gets
  address1 = line.strip.gsub(/\,/,"") #needed for some random commas
  line = infile.gets
  address2 = line.strip.gsub(/\,/,"")
  line = infile.gets
  city = line[21, 20].strip.gsub(/\,/,"")
  state = line[42, 2]
  zip = line[45, 5]
  record = [name, expire_date,last_used, address1, address2, city, state, zip]
  raw_records << record
  #counter = counter + 1
 end

end
infile.close
puts raw_records.map {|record| record*','}

File.open('test_w.txt', 'w') do |f2|   
f2.puts raw_records.map {|record| record*','} 
end


end

#the_string.gsub(/\,/,"")


load_file

I also wanted it save to a file and I used this:

File.open('test_w.txt', 'w') do |f2|   
f2.puts raw_records.map {|record| record*','} 
end

Answer 1

如果没有输入文件，很难给您任何代码作为示例，但文件的图像看起来相当可预测，因此具有一些 RegExp 魔法的状态跟踪器应该可以解决问题。

该文件看起来是制表符分隔的，因此您可以按制表符拆分行:

File.open('filename', 'r') do |file|
  lines = file.inject([]){|memo, line| memo.push line.split(/\t/)}
  # Now you have an array of arrays that you can parse with a state tracker
end

您的状态跟踪器将简单地跟踪您最后输入的内容，例如号码、姓名或发布日期，然后填充正确的值。
