title: How to get xml output in a file with new line using python xml.etree?
body: <p>I am generating xml file using "from xml.etree import ElementTree" and placing the generated output in to a new file "test.xml". The output is getting placed inside the test.xml but there is no new line its a big big line. So, what shall i do to have new line inside "test.xml" . Following is the script:</p>
  
  <pre><code>from xml.etree import ElementTree
  from xml.dom import minidom
  from lxml import etree
  def prettify(elem):
      """Return a pretty-printed XML string for the Element.
      """
      rough_string = ElementTree.tostring(elem, 'utf-8')
      reparsed = minidom.parseString(rough_string)
      return reparsed.toprettyxml(indent="  ")
  top = Element('my_document')
  comment = Comment('Practising')
  top.append(comment)
  child = SubElement(top, 'my_information')
  childs = SubElement(child,'my_name')
  childs.text = 'This child contains text.'
  print prettify(top)
  file = open("test.xml", 'w')
  xml.ElementTree(top).write(file)
  file.close()
  </code></pre>
