Problem with newlines when I use toprettyxml()

I found another great solution :

f = open(filename, 'w')
dom_string = dom1.toprettyxml(encoding='UTF-8')
dom_string = os.linesep.join([s for s in dom_string.splitlines() if s.strip()])
f.write(dom_string)
f.close()

Above solution basically removes the unwanted newlines from the dom_string which are generated by toprettyxml().

Inputs taken from -> What's a quick one-liner to remove empty lines from a python string?

toprettyxml() is quite awful. It is not a matter of Windows and '\r\n'. Trying any string as the newlparameter shows that too many lines are being added. Not only that, but other blanks (that may cause you problems when a machine reads the xml) are also added.
