title: Convert the blob content of my word document into String in apex controller
body: <p>On SalesForce ,</p>
  
  <p>I've got a word document as an attachment of a custom object, i can get it as blob by selecting the body of the attachment with a SOQL query :</p>
  
  <p>Attachment att = [ SELECT Body FROM Attachment WHERE PARENTID = '<strong><em>*</em>*</strong>' and ContentType='application/msword']   ;
  Blob b = att.body ;</p>
  
  <p>I tried to use the b.toString() function to have the content, but it didn't work.So is there any other way to convert the blob into a string that represent the text written in my word document.</p>
