URL Validity

Few days ago NewsFromNepal was asking me for some help on some URL validation code. The task was to verify a list of URLs and print the title of the page if it's valid/working. Here's a simple Python script to do that. The URLs are stored per line in url.txt

#! /usr/bin/python
# URL Validity

import urllib2
import re

urls = open('urls.txt', 'r').readlines()
badurls = []

print "Working URLs:",
for url in urls:
    try:
        handle = urllib2.urlopen(url)
        html = handle.read()
        match = re.search("<title>(.*)</title>",html)

        print "\n", url.strip(), " -> ",
        if match:
            print match.groups()[0],
    except:
        badurls.append(url)

if badurls:
    print "\nBad URLs:"
    for bad in badurls:
        print bad.strip()
