hello ya all. i have a problem again. still trying to extract url from the 
web. but now i need to extract multiple url and not just one. i ahve tried 
using findall() but all i get is the 'http' and nothing else.

http_url=r'''
    (http|https|ftp|wais|telnet|mailto|gopher|file)
    :
    [\w.#@&=\,-_~/;:\n]+
    (?=([,.:;\-?!\s]))
'''
http_re=re.compile(http_url, re.X)

p=http_re.findall("http:\\www.hotmial.com abnd http:\\www.my.com")
print p

this was very helpful and very confusing. after reading more on it i am only 
more confused with all the simbols. (?=...) what does this mean. i read it 
up but still am having trouble using it and underdtanding how it works. and 
i still cannot extract more than one url. tried many other ways but this is 
the only one with a bit of progress(the 'http')
well sorry for being so muxh trouble but your help is appreciated. thank you
