Scraping Data from a website which uses Power BI - retrieving data from Power BI on a website

Question

The code I used to read data is as follows. As mentioned, the order of the produced data differs from what is rendered on the browser:

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

options = webdriver.ChromeOptions()
options.binary_location = "C:/Program Files (x86)/Google/Chrome/Application/chrome.exe"
driver = webdriver.Chrome(options=options, executable_path="C:/Drivers/chromedriver.exe")

driver.get("https://app.powerbi.com/view?r=eyJrIjoiYjVjM2MyNjItZDE1Mi00OWI1LWE5YWYtODY4M2FhYjU4ZDU1IiwidCI6ImExMmNlNTRiLTNkM2QtNDM0Ni05NWVmLWZmMTNjYTVkZDQ3ZCJ9")
parent = driver.find_element_by_xpath('//*[@id="pvExplorationHost"]/div/div/div/div[2]/div/div[2]/div[2]/visual-container[4]/div/div[3]/visual/div')
children = parent.find_elements_by_xpath('.//*')
values = [child.get_attribute('title') for child in children]

I appreciate solutions for any of the above problems. The most interesting for me though, is the convention of storing Power BI data in JSON format.

Answer 1

Putting the scroll part and the JSON aside, I managed to read the data. The key is to read all of the elements inside the parent (which is done in the question):

parent = driver.find_element_by_xpath('//*[@id="pvExplorationHost"]/div/div/div/div[2]/div/div[2]/div[2]/visual-container[4]/div/div[3]/visual/div')
children = parent.find_elements_by_xpath('.//*')

Then sort them using their location:

x = [child.location['x'] for child in children]
y = [child.location['y'] for child in children]
index = np.lexsort((x,y))

To sort what we have read in different lines, this code may help:

rows = []
row = []
last_line = y[index[0]]
for i in index:
    if last_line != y[i]:
        row.append[children[i].get_attribute('title')]
    else:
        rows.append(row)
        row = list([children[i].get_attribute('title')]
rows.append(row)
