Answer 1

There may be better way-

Way -1

Below is my tested code to extract width and height.

from bs4 import BeautifulSoup

html_doc = '''

    Journal of     Infection (2015) 
    
    xx
    , 1
    e
    4
    

    
'''

soup = BeautifulSoup(html_doc,'html.parser')    
my_att = [i.attrs['style'] for  i in soup.find_all("div")]
dd = ''.join(my_att).split(";")
dd_cln= filter(None, dd)
dd_cln= [i.strip() for i in dd_cln ]
my_dict = dict(i.split(':') for i  in dd_cln)
print my_dict['width']

Way-2 Use regular expression as described here.

Working code-

import numpy as np
import re
from bs4 import BeautifulSoup

html_doc = '''

    Journal of     Infection (2015) 
    
    xx
    , 1
    e
    4
    

    
'''

soup = BeautifulSoup(html_doc,'html.parser')    
my_att = [i.attrs['style'] for  i in soup.find_all("div")]
css = ''.join(my_att)
print css
width_list = map(float,re.findall(r'(?<=width:)(\d+)(?=px;)', css))
height_list = map(float,re.findall(r'(?<=height:)(\d+)(?=px;)', css))
print np.mean(height_list)
print np.mean(width_list)
