Help parsing a page with python

I would like to parse a webpage to can get the url of the video download. I use python and firebug but I cant get the url link.

Example:

The url where I have to get the video link is: hxxp://www.rtve.es/mediateca/videos/20100开发者_如何学Go125/saber-comer---salsa-verde-judiones-25-01-10/676590.shtml"

The video is hxxp://www.rtve.es/resources/TE_SSAC011/flv/8/2/1264426362028.flv Could you help me please? Many thanks and sorry for my english!

Use BeautifulSoup or lxml.

import re 
from urllib2 import urlopen
text = urlopen('http://www.rtve.es/mediateca/videos/20100125/saber-comer---salsa-verde-judiones-25-01-10/676590.shtm').read()
reg = re.compile(r'http://www\.rtv.*flv')
reg.findall(text)

Normallly you can use this one. But there is no your link inside.
