Missing data using Beautiful soup-CodePudding

I'm trying to get the university names, scores and country names from this website: https://roundranking.com/ranking/world-university-rankings.html#world-2021 I can find the table where the data is by class, but the data which is in the <tbody> part of table is just disappears when I try to find it with Beautiful soup.

Here is the original html code:

<table  style="padding: 0px;">
<thead >
<tr><th >Rank</th><th  style="background-color: rgb(198, 235, 178);">University</th><th >Score</th><th >Country</th><th >Flag</th><th >League</th></tr>
</thead><thead  style="display: none; opacity: 0;">
<tr><th >Rank</th><th  style="background-color: rgb(198, 235, 178);">University</th><th >Score</th><th >Country</th><th >Flag</th><th >League</th></tr>
</thead>
<tbody>
<tr ><td >1</td><td ><a href="/universities/harvard-university.html?sort=O&amp;year=2021&amp;subject=SO">Harvard University</a></td><td >100.000</td><td >USA</td><td ><img src="../images_rur/Flag/Flag_USA.png" alt=""></td><td >Diamond League</td>
...
</tbody>
</table>

And here is the html what the soup shows:

<table  style="padding: 0px;">
<thead >
<tr><th >Rank</th><th  style="background-color: rgb(198, 235, 178);">University</th><th >Score</th><th >Country</th><th >Flag</th><th >League</th></tr>
</thead><thead  style="display: none; opacity: 0;">
<tr><th >Rank</th><th  style="background-color: rgb(198, 235, 178);">University</th><th >Score</th><th >Country</th><th >Flag</th><th >League</th></tr>
</thead>
</table>

My python code trying to get tha data:

import selenium
from selenium import webdriver
from bs4 import BeautifulSoup

driver = webdriver.Chrome('./chromedriver.exe')
driver.get('https://roundranking.com/ranking/world-university-rankings.html#world-2021')

source = driver.page_source
soup=BeautifulSoup(source)
#soup = BeautifulSoup(source, 'html5lib')
#soup = BeautifulSoup(source, 'html.parser')
#soup = BeautifulSoup(source, 'lxml')

soup.prettify

table=soup.find('table', {'class':'big-table table-sortable uci'})
print(table)

I've tried html5lib, lxml and html.parser but nothing works, when I print out the table it does not contain the body part, which has the data I need.

CodePudding user response：

the table is generated by a java script, you can find the required query in the browser. here is an example

url = "https://roundranking.com/final/ranking-json18r.php"

payload = "t=2021&s=O&sa=SO&sc=All Countries"
response = requests.request("POST", url, data=payload)
for university in response.json():
    print(university['rank'], university['univ'], university['score'], university['economy'], university['league'])
