get image from website

I try to improve a recipe for calibre and replace the default cover image with the cover image of the current newspaper issue.The way to go has something to do with get_cover_url (link).There are two problems:The URL of the cover image changes every day.I know virtually nothing about python.I hope for a solution like this (in pseudo-code):OPEN URL "http://epaper.derstandarddigital.at/";coverElement = (SEARCH HTML-ELEMENT "<img>" WITH ID "imgPage2" AND CLASS "page");coverUrl = (GET HTML-ATTRIBUTE "src" FROM coverElement);RETURN coverUrl;Would there be a way to achieve this in python*) (using only python standard libraries)?*) Calibre-Recipes seem to be python code[edit]here's the solution a friend of mine offered:#!/usr/bin/env pythonimport urllibfrom time import strftimedef get_cover_url(self): highResolution = True date = strftime("%Y/%Y%m%d") # it is also possible for the past #date = '2012/20120503' urlP1 = 'http://epaper.derstandarddigital.at/' urlP2 = 'data_ep/STAN/' + date urlP3 = '/V.B1/' urlP4 = 'paper.htm' urlHTML = urlP1 + urlP2 + urlP3 + urlP4 htmlF = urllib.urlopen(urlHTML) htmlC = htmlF.read() # URL EXAMPLE: data_ep/STAN/2012/20120504/V.B1/pages/A3B6798F-2751-4D8D-A103-C5EF22F7ACBE.htm # consists of part2 + part3 + 'pages/' + code # 'pages/' has length 6, code has lenght 36 index = htmlC.find(urlP2) + len(urlP2 + urlP3) + 6 code = htmlC[index:index + 36] # URL EXAMPLE HIGH RESOLUTION: http://epaper.derstandarddigital.at/data_ep/STAN/2012/20120504/pagejpg/A3B6798F-2751-4D8D-A103-C5EF22F7ACBE_b.png # URL EXAMPLE LOW RESOLUTION: http://epaper.derstandarddigital.at/data_ep/STAN/2012/20120504/pagejpg/2AB52F71-11C1-4859-9114-CDCD79BEFDCB.png urlPic = urlP1 + urlP2 + '/pagejpg/' + code if highResolution: urlPic = urlPic + '_b' urlPic = urlPic + '.png' return urlPicif __name__ == '__main__': print get_cover_url(None)
