When I run this code in command line. I am getting following things

<?xml version="1.0"?>
<books>
  <book>
    <author>Jack Herrington</author>
    <Developer>I am developer </Developer>
    <title>PHP Hacks</title>
    <publisher>O'Reilly</publisher>
  </book>
  <book>
    <author>Jack Herrington</author>
    <Developer>I am developer </Developer>
    <title>Podcasting Hacks</title>
    <publisher>O'Reilly</publisher>
  </book>
</books>

When I run the code in web browser it gives me following things

Jack Herrington  I am developer  O'Reilly    Jack Herrington  I am developer  O'Reilly  

I want to above output to be like command line output. And one more things is that instead of displaying , how could I create a xml file using $doc Dom object.
