Initial Comment:
The following XML file was parsed, but could not be 
printed by minidom.

<?xml version="1.0" ?>
<test1 xmlns="uri:test.com">
  <test2 xmlns="">
     <test3>Hello</test3>
  </test2>
</test1>

>>> import xml.dom.minidom
>>> doc=xml.dom.minidom.parse('test.xml')
>>> print doc.toxml()
