Python BeautifulSoup can't get data from a specific attribute in a tag-CodePudding

I was trying to scrape data from this website of mihoyo and ran into a problem. I wanted to get data from the attribute 'data-src' in the first 'div' tag but I couldn't.

<a href="[not important]" target="_blank"  data-v-51c84696="">
  <div  data-v-51c84696="" data-src="[link to a png image that I need]" 
  lazy="loaded" style="[not important]">
    <div  data-v-51c84696="">
      <!---->
    </div>
  </div> 
</a>

My code was:

url = "https://bbs.mihoyo.com/bh3/wiki/channel/map/17/18?bbs_presentation_style=no_header"
result = requests.get(url).text
soup = BeautifulSoup(result, 'lxml')

a = soup.find('a' , class_ = 'collection-avatar__item')

b = a.find('div' , class_ = 'collection-avatar__icon')['data_src']

print(b)

It didn't print out anything.
Turned out the problem was in the 'div' tag. I printed out the whole 'div' tag:

<div  data-v-51c84696=""><div  data-v-51c84696=""><!-- --></div></div>

with the code:

print(a.find('div' , class_ = 'collection-avatar__icon'))

You can see that the 'data-src', 'style' and 'lazy' attributes in the'div' tag are all gone. It seems like the 'data-v-51c84696' blocks everything behind it but idk if it's true or not.
How can I get the 'data-src'?

P/s: If you want to try it yourself:

Go to this website right click on this character and click "Inspect". It will open the html and get you to the said 'div' tag.
Use this exact code. The code will print out the 'div' tag:

import requests
from bs4 import BeautifulSoup

url = "https://bbs.mihoyo.com/bh3/wiki/channel/map/17/18?bbs_presentation_style=no_header"
result = requests.get(url).text
soup = BeautifulSoup(result, 'lxml')

a = soup.find('a' , class_ = 'collection-avatar__item')

b = a.find('div' , class_ = 'collection-avatar__icon')

print(b)

CodePudding user response：

All icons are located in the script tag. We can write a small regular expression to search. But unfortunately this ll also include other unnecessary icons that require additional scraping.

import requests
import codecs
import re

url = "https://bbs.mihoyo.com/bh3/wiki/channel/map/17/18?bbs_presentation_style=no_header"
result = requests.get(url).text
urls = re.findall(r'icon:"https://uploadstatic.mihoyo.com/bh3-wiki/[\w/\-?=%.] \.[\w/\-&?=%.] \"',
                  codecs.decode(result, 'unicode-escape'))
for url in urls:
    print(url.split("\"")[1])
