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

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)

A few more details about exactly which data you are trying to scrap would have helped to construct a canonical answer. However, to scrape the data within the Commodity and Basis using Selenium, as the the desired element is within an <iframe> so you have to:

• Induce WebDriverWait for the desired frame_to_be_available_and_switch_to_it().
• Induce WebDriverWait for the desired visibility_of_element_located() for the table.
• Induce WebDriverWait for the desired visibility_of_all_elements_located() for the desired data.

• You can use the following Locator Strategies:

  • Code Block:

    from selenium import webdriver
    from selenium.webdriver.common.by import By
    from selenium.webdriver.support.ui import WebDriverWait
    from selenium.webdriver.support import expected_conditions as EC
    
    options = webdriver.ChromeOptions() 
    options.add_argument("start-maximized")
    options.add_experimental_option("excludeSwitches", ["enable-automation"])
    options.add_experimental_option('useAutomationExtension', False)
    driver = webdriver.Chrome(options=options, executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')
    driver.get("https://ahdb.org.uk/cereals-oilseeds/feed-ingredient-prices")
    WebDriverWait(driver, 20).until(EC.frame_to_be_available_and_switch_to_it((By.TAG_NAME,"iframe")))
    WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.CSS_SELECTOR, "div.innerContainer")))
    print("Commodity:")
    print([my_elem.text for my_elem in WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.XPATH, "//div[@class='pivotTableCellWrap cell-interactive tablixAlignLeft ' and starts-with(@title, 'Ex-')]//parent::div//preceding::div[1]")))])
    print("-=-=-=-=-=-")
    print("Basis:")
    print([my_elem.text for my_elem in WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.CSS_SELECTOR, "div.pivotTableCellWrap.cell-interactive.tablixAlignLeft[title^='Ex-']")))])
    

  • Console Output:

    Commodity:
    ['Argentine Sunflowermeal 32/33%', 'Maize Gluten Feed', 'Pelleted Wheat Feed', 'Rapemeal (34%)', 'Soyameal (Hi Pro)', 'Soyameal, Brazilian (48%)']
    -=-=-=-=-=-
    Basis:
    ['Ex-Store Liverpool', 'Ex-Store Liverpool', 'Ex-Mill Midlands and Southern Mills', 'Ex-Mill Erith', 'Ex-Store East Coast', 'Ex-Store Liverpool']

Update (as per bounty explanation)

As per your comment as well as the given link on the bounty explanation, to scrape the data from Page 2 within the table under the heading Scouting Location using Selenium, you can use the following solution. For the sake of demonstration I have created a List of first 20 countries and you can expand as much as you wish:

• Code Block:

  from selenium import webdriver
  from selenium.webdriver.support.ui import WebDriverWait
  from selenium.webdriver.common.by import By
  from selenium.webdriver.support import expected_conditions as EC
  
  options = webdriver.ChromeOptions() 
  options.add_argument("start-maximized")
  options.add_experimental_option("excludeSwitches", ["enable-automation"])
  options.add_experimental_option('useAutomationExtension', False)
  driver = webdriver.Chrome(options=options, executable_path=r'C:\WebDrivers\chromedriver.exe')
  driver.get("https://app.powerbi.com/view?r=eyJrIjoiMzE1ODNmYzQtMWZhYS00NTNjLTg1MDUtOTQ2MGMyNDVkZTY3IiwidCI6IjE2M2FjNDY4LWFiYjgtNDRkMC04MWZkLWQ5ZGIxNWUzYWY5NiIsImMiOjh9")
  WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//span[@class='navigation-wrapper navigation-wrapper-big']//i[@title='Next Page']"))).click()
  print("Country:")
  print([my_elem.text for my_elem in WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.XPATH, "//div[@class='bodyCells']//div[@class='pivotTableCellWrap cell-interactive ']")))[:20]])
  driver.quit()
