Python Regex to find image source

Question

I am new to Python and I am trying to get alt and images source from a website, but I am facing problem with the quote ' and "

import requests,urllib,urllib2,re

rule = re.compile(r'^[^*$<,>?!\']*$')

r = requests.get('http://www.hotstar.com/channels/star-plus')
match = re.compile('<img alt="(.*?)" ng-mouseleave="mouseLeaveCard()" ng-mouseenter="mouseEnterCard()" ng-click="mouseEnterCard(true)" ng-class="{\'dull-img\': isThumbnailTitleVisible || isRegionalLanguageVisible}" class="show-card imgtag card-minheight-hc ng-scope ng-isolate-scope" placeholder-img="{\'realUrl\' :  \'(.*?)\', \'placeholderUrl\' : \'./img/placeholder/hs.jpg\'}" ng-if="record.urlPictures" src="(.*?)" style="display: block;">',re.DOTALL).findall(r.content)
for name,img,image in match:

I can only use the standard Python library.

I've read about defining rule so I did from this: Regex Apostrophe how to match?

Honestly, I don't know how to use it.

Thanks in advance

Use a parser instead:

import requests
from bs4 import BeautifulSoup
r = requests.get('http://www.hotstar.com/channels/star-plus')
soup = BeautifulSoup(r.text, "lxml")
imgs = soup.findAll('img')
for img in imgs:
    print(img["alt"])

This gives me the following output: * – Ohumeronen Jul 28 '16 at 13:37
@Ohumeronen: I know. It prints out all the `alt` attributes of each image found. – Jan Jul 28 '16 at 13:41
@Jan i am also getting output as `*` nothing else – Mark Pole Jul 29 '16 at 06:18
@MarkPole: What exactly do you want as output? The image source? Just change it to `img['src']` then. – Jan Jul 29 '16 at 06:20
