Detect comments part using web scraping

[seco]

Hi
I'm following this tutorial to scrape Ajax comments section from a website https://likegeeks.com/python-web-scraping/

I'm using both beautifulSoup and selenium to scrape Ajax comments.
The article shows how to scrape ajax content, but I'm asking:
Is there a way to detect that this section is the content section regardless the scraped website? like an advanced scraping library or so?

Thanks in advance.
