python - How to retrieve these elements from a webpage? -


i have webpage in html these elements:

<div class="content_page">     <a href="/earth" class="nametessera" >earth</a> </div> <div class="content_page">     <a href="/world" class="nametessera" >world</a> </div> <div class="content_page">     <a href="/planet" class="nametessera">planet</a> </div> ...

i need retrieve /earth, /world, /planet, etc. need retrieve links of tag class "nametessera".

how can python ?

short answer:

use beautifulsoup parse page, urls , use urlib2 or pycurl download mentioned urls.

[edit:]

adding on examples below use the href contained in div

>>> alldiv = soup.findall('div', { "class" : "content_page" }) >>> div in alldiv: print div.a ...  <a href="/earth" class="nametessera">earth</a> <a href="/world" class="nametessera">world</a> <a href="/planet" class="nametessera">planet</a> >>> div in alldiv: print div.a['href'] ...  /earth /world /plan

similarly 

allhref = soup.findall('a', { "class" : "nametessera" })
