以特定格式从 pdf 中提取数据

问：

我想以哈希的形式提取数据。文字是这样的。有时有一个逮捕类型和多个指控和指控描述，有时有一个逮捕类型和一个指控和指控描述。有时是多种逮捕类型和多种指控描述。我想要从下面的文本中得到这样的输出

   {  Arrest Type=>  Out Of County Warrant, charge => 11378 HS , Charge Description => POSS CNTL SUB FOR SALE  ,  Arrest Type=>  Out Of County Warrant,  charge => 11379(A) HS   , Charge Description => TRANSP/ETC CNTL SUB  }

   {  Arrest Type=>   Bench Warrant, charge => 1203.2 PC , Charge Description =>  PROB VIOL:REARREST/REVOKE   }

 { Arrest Type=>   On View, charge => 11364 HS   , Charge Description =>  CNTL SUB PARAPHERNALIA , 
   Arrest Type=>   On View, charge => 488 PC  , Charge Description =>  PETTY THEFT,
   Arrest Type=>   Out Of County Warrant,  charge =>  487(C) PC  , Charge Description =>  GRAND THEFT FROM PERSON  }

这是我尝试过的一段代码。如何获得所需的输出？

total_page.scan(/Arrest Type\s+(.*?)\s+(Charge\s+(.*?)\s+Charge Description\s+(.*?)\s+|((?:Charge\s+(.*?)\s+Charge Description\s+(.*?)\s+)+)?)(?=Arrest Type|Name\z)/m).each do |match|
  arrest_type = match[0].strip
  charge_data = match[1].split(/\s{2,}/)

  (0...charge_data.length).step(2) do |i|
    new_hash = {
      "Arrest Type" => arrest_type,
      "charge" => charge_data[i],
      "Charge Description" => charge_data[i+1]
    }
    arrest_data << new_hash
  end
end

# print the resulting array of hashes
arrest_data.each do |arrest|
  p arrest
end
