title: PDF to XML conversion using PHP
body: <p>I need help to convert PDF to XML using PHP.
  There are some sites which claims to do so. But they charge for that.
  I have to write my own code in PHP for that.
  Being a novice in PHP I don't know how to approach this task.
  So if anyone had worked on it plz help me with this.</p>
  
  <p>Any help would be highly appreciated.</p>
