minidom documents expose methods .toxml and .toprettyxml that you
can use for your purposes.  For example:

>>> import xml.dom.minidom
>>> tree = xml.dom.minidom.parseString('<foo>one<bar>two</bar>3</foo>')
>>> print tree.toxml()
<?xml version="1.0" ?>
<foo>one<bar>two</bar>3</foo>
>>> print tree.toprettyxml()
<?xml version="1.0" ?>
<foo>
        one
        <bar>
                two
        </bar>
        3
</foo>
