Some sites return a list that you may want or need to munge into links.
An example would be LinuxToday.com.
Add this to the above, and you it will return a list ready for
formatting.

def fetch_list(uri):
	from httplib import HTTP
	from urlparse import urlparse

	parsed_uri=urlparse(uri)

	h = HTTP(parsed_uri[1])
	h.putrequest('GET', parsed_uri[2])
	h.putheader('Accept', 'text/html')
	h.putheader('Accept', 'text/plain')
	h.endheaders()
	errcode, errmsg, headers = h.getreply()
	items=[]
	if errcode == 200:
		f = h.getfile()
		for line in  f.readlines():
			items.append(line)
		return items

Of coourse, this means that unless it is a list of links, complete with
HTML, you will need to do some splitting of the string returned in the
list, but it will be a start.

I am looking at making this into something that can be integrated with
the PTK ... along with KnowledgeKit. No promises on a timeframe ;) ( I
do have an intermediary PTK-Aware KnowledgeKit if anyone wants it, I'll
put it up for grabs.).

An example of the use of the lists visit http://www.libc.org/TheIgloo .
