Not at all. Not with all subpackages; primarily, just minidom is 
included (and pulldom and the DOM builder).

Use xml.dom.minidom.parse instead.

Use xml.dom.minidom instead. If you need a DOMImplementation,
use xml.dom.getDOMImplementation(). If you need to create
nodes and such, use the relevant create* factory method on
the document.

Use toxml/toprettyxml instead.

Correct. What you currently uses is called a "DOM builder" (i.e.
an algorithm that creates a DOM tree) out of SAX2 events.
So it consumes SAX events and produces a DOM tree. Python comes
with a different such builder out of the box.
