Python Comparing Strings Help

[Sundown]

Hello... This is my first time posting. One of my co workers told me this is the place to be for help on these kinds of situations. Anyhow this is what I got:

I am trying to make a simple anti phishing script in python. I need help figuring how to look at a simple html source statement such as this (below)and then have the program spit back "bad news" or so forth.

#! /usr/bin/python
# scan.py
import sys,string,re
f = open(sys.argv[1])
lines = f.readlines()
string = string.join(lines,"")
# I or IGNORECASE for case insensitive, S or DOTALL for . matches \n
phmatch = re.search(r'(secure).*?(phishing)',string,re.IGNORECASE | re.DOTALL)
if phmatch:
  print "Looks like a phishing scam."
  print "Redirection from %s to %s." % (phmatch.group(1),phmatch.group(2))
else:
  print "Looks Ok."
