I am trying to scrape a table from a Javascript website using Pandas. For this, I used Selenium to first reach my desired page. I am able to print the table in text format (as shown in mented script), but I want to be able to have the table in Pandas, too. I am attaching my script as below and I hope someone could help me figure this out.

import time
from selenium import webdriver
import pandas as pd

chrome_path = r"Path to chrome driver"
driver = webdriver.Chrome(chrome_path)
url = '/?
filter=BS02'

page = driver.get(url)
time.sleep(2)


driver.find_element_by_xpath('//*[@id="bursa_boards"]/option[2]').click()


driver.find_element_by_xpath('//*[@id="bursa_sectors"]/option[11]').click()
time.sleep(2)

driver.find_element_by_xpath('//*[@id="bm_equity_price_search"]').click()
time.sleep(5)

target = driver.find_elements_by_id('bm_equities_prices_table')
##for data in target:
##    print (data.text)

for data in target:
    dfs = pd.read_html(target,match = '+')
for df in dfs:
    print (df)  

Running the above script, i get the below error:

Traceback (most recent call last):

You can get the table using the following code

import time
from selenium import webdriver
import pandas as pd

chrome_path = r"Path to chrome driver"
driver = webdriver.Chrome(chrome_path)
url = 'http://www.bursamalaysia./market/securities/equities/prices/#/?filter=BS02'

page = driver.get(url)
time.sleep(2)

df = pd.read_html(driver.page_source)[0]
print(df.head())

This is the output

To get data from all pages you can crawl the remaining pages and use df.append

Answer:

df = pd.read_html(target[0].get_attribute('outerHTML'))

Result:

Reason for target[0]:

driver.find_elements_by_id('bm_equities_prices_table') returns a list of selenium webelements, in your case, there's only 1 element, hence [0]

Reason for get_attribute('outerHTML'):

we want to get the 'html' of the element. There are 2 types of such get_attribute methods: 'innerHTML' vs 'outerHTML'. We chose the 'outerHTML' becasue we need to include the current element, where the table headers are, I suppose, instead of only the inner contents of the element.

Reason for df[0]

pd.read_html() returns a list of data frames, the first of which is the result we want, hence [0].
