DOM text to xml aarrgghhh!!!!

[huntermorgan]

hi there, ive posted b4 but was mentioned that my request was a bit
vague so.....im a tertiary student getting my head around python and
im liking python but not quite handy with the syntax etc...so im
really needing help on this one

i would like to have someone look at my code below and answer as to
what i have done that makes my small program not work and some code to
fix it.

it is a small python coded program that takes in a tertiary course
outline ("Outline2003") in a text format and should output it in an
xml styled text format. hence, text in = xml out.

at the moment the output file reads this

<?xml version="1.0" ?>
<2003 Course Outline/>

...and thats it. There are headings and sub-headings which should
format to xml tags and the text in between should just be written to
the output as is, in between the tags.

so please...im desperate to figure out why my code wont work.

can anybody help???? below is the code and below that is a small
snipet of the course outline

<start of code>

import re
from xml.dom.minidom import *

def main(arg):
    try:
        f = open(arg)
    except:
        print "cannot open file"


    newdocument = Document()
    rootElement = newdocument.createElement("2003 Course Outline")
    newdocument.appendChild(rootElement)
    
    tagSequence = re.compile("(^\d+)\t+")
    
    while 1:
        line = f.readline()
        if not line:
            break

        s = line

        target = tagSequence.search(s)
        if target:
            s2 = re.search("\t", s)
            result = s[s2.span()[1]:]
            newElement = newdocument.createElement(result)
            newDocument.appendChild(newElement)
    
    x = newdocument.toxml()
    f=open('CourseOutlineXML.xml', 'w')
    f.write(x)
    print x
                      
if __name__ == '__main__':
    main("Outline2003.txt")
