How do I get the width inside of style inside of class of span?-CodePudding

I'm trying to get the result out so that I'll be able to get what's inside of "width: 100%" and only the number part. I'm using beautifulsoup python. and my code is here for getting it:

rating_data.append(e.select_one('.review-list__rating__active'))

but it keeps giving me the whole entire line which is

<span  style="width: 100%">

above result. I'm trying to get the value inside of the width. is that any possible using beautifulsoup, python? Thanks guys.

To get the values of an attribute use get():

e.select_one('.review-list__rating__active').get('style')

If there is only one style you could use split() to get the value:

e.select_one('.review-list__rating__active').get('style').split(':')[-1]

If there are multiple you have to iterate:

for s in e.select_one('.review-list__rating__active').get('style').split(';'):
    if 'with' in s:
        print(s.split(':')[-1])

Another alternativ would be to use regex.

The cssutils library can help with this:

from bs4 import BeautifulSoup
import cssutils

html = """<span  style="width: 100%"></span>"""

soup = BeautifulSoup(html, "html.parser")
span_style = soup.select_one('.review-list__rating__active')['style']
style = cssutils.parseStyle(span_style)

print(style.width)

This displays:

100%
