    A tiny example showing a simple XML tree traversal using
    the xml.dom.minidom module.

import sys
from xml.dom.minidom import parse, Node

def traverseTree(node, indentation):
    if node.nodeType == Node.ELEMENT_NODE:
        print '%sTAG: /%s/' % (indentation, node.tagName)
    elif node.nodeType == Node.TEXT_NODE:
        print '%sTEXT: /%s/' % (indentation, node.data)
    else:
        print '%sOther type: /%s/' % (indentation, str(node.nodeType))

    for child in node.childNodes:
        traverseTree(child, indentation + '  ')

if __name__ == '__main__':
    if len(sys.argv) != 2:
        print >>sys.stderr, 'Usage: %s xmlfile' % sys.argv[0]
        exit()

    document = parse(sys.argv[1])
    traverseTree(document.documentElement, '')
