Answer 1

language: Python
library: BeautifulSoup

from BeautifulSoup import BeautifulSoup

html = ""
for link in ("foo", "bar", "baz"):
    html += '%s' % (link, link)
html += ""

soup = BeautifulSoup(html)
links = soup.findAll('a', href=True) # find  with a defined href attribute
print links  

output:

[foo,
 bar,
 baz]

also possible:

for link in links:
    print link['href']

output:

http://foo.com
http://bar.com
http://baz.com
