You can use this to parse your file:

with open('niktoscan.txt') as f:
    content = f.readlines()

foundone = False
print type(content)

cleanedContent = []
for line in content:
    print line

    foundnik = line.find('<niktoscan')
    if not (foundnik != -1 and foundone):
        cleanedContent.append(line)

    if foundnik != -1:
        foundone = True
print "\n\n ########### cleaned content ########### \n\n"

for line in cleanedContent:
    print line

Then you can put the results through your parser.
