Addressing your general question, unfortunately you're a bit stuck.
Minidom is rather confused about whether or not it's a namespace aware
library.  Addressing your specific example, I strongly advise you not
to use documents that are not well-formed according to Namespaces 1.0.
Your second example is a well-formed XML 1.0 external parsed entity,
but not a well-formed XML 1.0 document entity, because it has multiple
elements at document level.  It's also not well-formed according to
XMLNS 1.0 unless you declare the "title" prefix.  You will not be able
to use a non XMLNS 1.0 document with most XML technologies, including
XSLT, WXS, RELAX NG, etc.

If you have indeed declared a namespace and are just giving us a very
bad example, use:

print doc.getElementsByTagNameNS(title_namespace, 'id')
