For this particular case, BeautifulSoup is harder to write than a regex, but it is much more robust... I'm just contributing with the BeautifulSoup example, given that you already know which regexp to use :-)

html_data = open('/yourwebsite/page.html','r').read()

#Create the soup object from the HTML data
soup = BeautifulSoup(html_data)
fooId = soup.find('input',name='fooId',type='hidden') #Find the proper tag
value = fooId.attrs[2][1] #The value of the third attribute of the desired tag 
                          #or index it directly via fooId['value']
