Web Scraping Got Empty Array Values

Question

Hello All I was trying to scrape a stock website to get stock sector wise info in this website.

I just hit scrapy shell in terminal if the data is acheivable for this table

In the terminal this was my command
after I ran scrapy shell "https://nepsealpha.com/"
response.xpath("//table[@id='fixTable']//tbody//tr")

but the output I get is empty list = []

I feel content is being rendered with javascript
anyway I can do without use of selenium?

The data you’re after comes from an API endpoint.

You can get it and then massage it back to the form of a table or use only parts of it.

Here’s how:

import requests

import pandas as pd

api_endpoint = "https://nepsealpha.com/api/smx9841/dashboard_board"

payload = {
    "_token": "K5fwARzoE7j49mIE5hdeZUqeoYgQGUXnsUeS7SG1"
}

headers = {
    "Accept": "application/json",
    "User-Agent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/91.0.4472.114 Safari/537.36",
    "X-Requested-With": "XMLHttpRequest",
}

response = requests.request("POST", api_endpoint, headers=headers, data=payload)
data = response.json()["home_table"]
df = pd.json_normalize(data)
print(df)

Output:
