title: How to parse yaml in ruby without type mapping
body: <p>I would like to get data from a Mysql dump in yaml (PHPMyAdmin), but data are not surrounded by quotation mark. </p>
  
  <p>I have zipcode that can start by 0 and after parsing I get decimal version of octal value, in place of simple string. </p>
  
  <p>How can I do to force Yaml parser not to do  auto-mapping, or just get all data as they are string ?</p>
  
  <p>Thanks</p>
  
  <p>== UPDATE == </p>
