Hi all,

I'm new to this list (and python ;-)) and working on a small personal project. 

I'm basically using the twill to browse a website (weather reports) and do a re
search for a specific string that once found, needs to be printed in a web page
on it's own. The problem I found with twill is that it also prints the html that
comes along with it. (Apparently it's a known "functionality")

The way around this was for me to write my regexp find to another file and then
display that in another cgi script, surely there must be a cleaner way of doing
it? Also, any idea how I can call the second script from the first after the
first one is finished?

Any ideas appreciated. Code below.( No laughing please!)



import cgitb; cgitb.enable()  # only for temp debugging
import re
import cgi
from twill.commands import *

url = "http://secure.metoffice.com/logon.jsp"
fv(1, 'username', 'xxxxxxxx')
fv(1, 'password', 'xxxxxxxx')

report = show()
result = re.search("EGKB.*</td>",report)
result = re.sub("</td>", "", result.group())

file = open('/var/www/cgi-bin/results.txt', 'w')
print >>file, result 

And then my second script runs this to display the one liner:

import cgi
import cgitb; cgitb.enable() # again only for temp debugging.

def dispmetar():
        f = open('results.txt', 'r')
        data = f.readlines()

        print 'Content-Type: text/html'

        for line in data:
                print "<u>METAR</u>: " + line


Just playing around with creating my own functions as you can tell...
