CGI Hello Browser

#!/usr/bin/python

import cgi, urllib2, html5lib, urlparse
import cgitb; cgitb.enable()

print "Content-type: text/html"
print

q = cgi.FieldStorage()
url = q.getvalue("url","http://pzwart3.wdka.hro.nl/wiki")
f = urllib2.urlopen(url)
t = html5lib.parse(f,treebuilder="etree",namespaceHTMLElements=False)

print f.info().get("content-type")

for a in t.iter("a"):
    href = a.get("href")
    href = urlparse.urljoin(url, href)
    print '<a href="?url={0}">{0}</a><br>'.format(href)

#links = list(t.iter("a"))
#l = links[0]

#print f.read()
#print "hello"
