Trouble Scraping site with BS4

usually I'm able to write a script that works for scraping, but I've been having some difficulty scraping this site for the table enlisted for this research project I'm working on. I'm planning to verify the script working on one State before entering the URL of my targeted states.

import requests
import bs4 as bs

url = ("http://programs.dsireusa.org/system/program/detail/284")
dsire_get = requests.get(url)
soup = bs.BeautifulSoup(dsire_get.text,'lxml')
table = soup.findAll('div', {'data-ng-controller': 'DetailsPageCtrl'})
print(table) 
#I'm printing "Table" just to ensure that the table information I'm looking for is within this sections

I'm not sure if the site is attempting to block people from scraping, but all the info that I'm looking to grab is within "&quot"if you look what Table outputs.

So I finally managed to solve the issue, and successfuly grab the data from the Javascript page the code as follows worked for me if anyone encounters a same issue when trying to use python to scrape a javascript webpage using windows (dryscrape incompatible).

import bs4 as bs
from selenium import webdriver  
from selenium.common.exceptions import NoSuchElementException  
from selenium.webdriver.common.keys import Keys
browser = webdriver.Chrome()
url = ("http://programs.dsireusa.org/system/program/detail/284")
browser.get(url)
html_source = browser.page_source
browser.quit()
soup = bs.BeautifulSoup(html_source, "html.parser")
table = soup.find('div', {'class': 'programOverview'})
data = []
for n in table.findAll("div", {"class": "ng-binding"}):
    trip = str(n.text)
    data.append(trip)

The text is rendered with JavaScript. First render the page with dryscrape

(If you don't want to use dryscrape see Web-scraping JavaScript page with Python )

Then the text can be extracted, after it has been rendered, from a different position on the page i.e the place it has been rendered to.

As an example this code will extract HTML from the summary.

import bs4 as bs
import dryscrape

url = ("http://programs.dsireusa.org/system/program/detail/284")
session = dryscrape.Session()
session.visit(url)
dsire_get = session.body()
soup = bs.BeautifulSoup(dsire_get,'html.parser')
table = soup.findAll('div', {'class': 'programSummary ng-binding'})
print(table[0])

Outputs:

<div class="programSummary ng-binding" data-ng-bind-html="program.summary"><p>
