Thank you for the reply.

My problem was that i had an element and had created a textnode with a
public certificate and then appended it as a child to the element.
Problem is writexml(), toxml() when given '\n' for pretty printing add a
newline between the element and the text node. So
So my third party wants -

<element>----BEGIN CERTIFICATE
.. ....
</element>


and we give him

<element>
-----BEGIN CERITIFICATE
......
</element>



>>> import xml.dom.minidom as md
>>> doc = md.Document()
>>> e = doc.createElement("element")
>>> t = doc.createTextNode("----BEGIN CERT---- blah blah ---END---CERT---")
>>> e.appendChild(t)
<DOM Text node "----BEGIN ...">

>>> e.toxml()
'<element>----BEGIN CERT---- blah blah ---END---CERT---</element>'

>>> e.toprettyxml()
'<element>\n\t----BEGIN CERT---- blah blah ---END---CERT---\n</element>\n'

So was using writexml('\t', '\n') so as the xml is readable and it added a
newline after the element and before the text node causing my third party
library to barf in agony.
