inserting newlines in xml file generated via xml.etree.ElementTree in python

Question

I have created a xml file using xml.etree.ElementTree in python. I then use

tree.write(filename, "UTF-8") 

to write out the documen

Answer 1

According to this thread your best bet would be installing pyXml and use that to prettyprint the ElementTree xml content (as ElementTree doesn't seem to have a prettyprinter by default in Python):

import xml.etree.ElementTree as ET

from xml.dom.ext.reader import Sax2
from xml.dom.ext import PrettyPrint
from StringIO import StringIO

def prettyPrintET(etNode):
    reader = Sax2.Reader()
    docNode = reader.fromString(ET.tostring(etNode))
    tmpStream = StringIO()
    PrettyPrint(docNode, stream=tmpStream)
    return tmpStream.getvalue()
