  <p>Si I want to search in this file by many criteria books, for example by author, by genre, price, etc...</p>
  
  <p>I will use XPath queries to do this, So is there some simple method to use???
  For example, I want to check if an author exist and to do this I must have a method in which I'll pass an XPath query to turn me the result...</p>
  
  <p>Thanks in advance,</p>
  
  <p>Best regards,</p>
