title: create XML from DTD
body: <p>I have two cases here.</p>
  
  <ol>
  <li><p>I am given a DTD and a text file and I need to create an XML file from it.</p></li>
  <li><p>I am given some data that needs to be updated in my XML Document and also a DTD is given.</p></li>
  </ol>
  
  <p>Since I have multiple documents (~1500 pages/book and there are 8 books), I want to know if I can  automate the above 2 cases. I'm using Altova XML Spy; I also have OxygenXML.</p>
  
  <p>Please let me know how can I achieve the above cases, this would be a great help to me.</p>
