Use xml etree ElementTree to print nicely formatted xml files

Question

I am trying to use xml etree ElementTree to write out xml files with Python  The issue is that they keep getting generated in a single line  I want to be able to easily reference them so if it s possible I would really like to be able to have the file written out cleanly   This is what I am getting    lt Language gt  lt En gt  lt Port gt Port lt  Port gt  lt UserName gt UserName lt  UserName gt  lt  En gt  lt Ch gt  lt Port gt IP   lt  Port gt  lt UserName gt      lt  UserName gt  lt  Ch gt  lt  Language gt    This is what I would like to see    lt Language gt       lt En gt           lt Port gt Port lt  Port gt           lt UserName gt UserName lt  UserName gt       lt  En gt       lt Ch gt           lt Port gt IP   lt  Port gt           lt UserName gt      lt  UserName gt       lt  Ch gt   lt  Language gt

You can use the function toprettyxml   from xml dom minidom in order to do that   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   t     The idea is to print your Element in a string  parse it using minidom and convert it again in XML using the toprettyxml function   Source  http   pymotw com 2 xml etree ElementTree create html
