Answer 1

Running your Python code with a few adjustments:

from xml.dom import minidom
Test_file = open('C:/test_file.xml','r')
xmldoc = minidom.parse(Test_file)

Test_file.close()

def printNode(node):
  print node
  for child in node.childNodes:
       printNode(child)

printNode(xmldoc.documentElement)

With this sample input as test_file.xml:

  testing 1
  testing 2

Yields this output:

Notes:

• As @LukeWoodward mentioned, avoid DOM-based libraries for large inputs, however 180K should be fine. For 180M, control may never return from minidom.parse() without running out of memory first (MemoryError).
• As @alecxe mentioned, you should eliminate the extraneous ':' in the file spec. You should have seen error output along the lines of IOError: [Errno 22] invalid mode ('r') or filename: 'C::/test_file.xml'.
• As @mzjn mentioned, xml.dom.minidom.Document is not iterable. You should have seen error output along the lines of TypeError: iteration over non-sequence.
