The write the same RE but explicitly without "body".  But I guess I didn't
understand your problem when the answer is that obvious.

Maybe you want to iterate over the text file line by line and match or
search within the line? Untested:

needle = re.compile(r'create\s+or\s+replace\s+package(\s+body)?\s+',
                    re.IGNORECASE)
for i, line in enumerate(lines):
    if needle.match(line):
        print 'match in line %d' % (i + 1)
