Outputting a Document

• Going from a a Document to its XML representation only requires calling toString() on it.
• A normalized XML document has no extraneous whitespace.
• In order to normalize your document call normalize() on it.
• To be complete your document will need the <?xml....> and <!DOCTYPE...> lines, these can be added:

try 
{
  File newFile = new File("processedOrders.xml");
  FileWriter newFileStream = new FileWriter(newFile);
  newFileStream.write("<?xml version=\"1.0\"?>");
  newFileStream.write("<!DOCTYPE "+doc.getDoctype().getName()+" ");
  if (doc.getDoctype().getSystemId() != null) 
  {
    newFileStream.write(" SYSTEM ");
    newFileStream.write(doc.getDoctype().getSystemId());   
  }
  if (doc.getDoctype().getPublicId() != null) 
  {
    newFileStream.write(" PUBLIC ");
    newFileStream.write(doc.getDoctype().getPublicId());   
  }
  newFileStream.write(">");
         
  newFileStream.write(newRoot.toString());

  newFileStream.close();

} catch (IOException e) {
  System.out.println("Can't write new file.");   
}
