使用不同的分隔符解析文本 - 使用分组

标签: ruby parsing text

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做一些解析来获取我需要的数据并输出文件。但是,输出将数据放在单独的行上,我需要将输出文件(name,expiry date,last_used,address1,address2,city,state,zip)放在用逗号分隔的一行上。

到目前为止,这是代码:

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

我还想将它保存到文件中,我使用了这个:

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

答案 0 :(得分:0)

如果没有输入文件,很难给你任何代码作为例子,但是文件的图像看起来相当可预测,所以带有一些RegExp魔法的状态跟踪器应该可以解决问题。

文件看起来以制表符分隔,因此您可以按标签分割行:

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

您的状态跟踪器只会跟踪您最后输入的内容,例如号码,名称或日期_发布,然后填充正确的值。
