Message on website content changed in Telegram

Description

I wanted a system to monitor website content changes and notify me. So I made it using n8n.

Especially my competitor blogs. I wanted to know how often they are posting new articles. (I used their sitemap.xml file) (The below workflow may vary)

In the Below example, I used HackerNews for example.

Explanation:

First HTTP Request node crawls the webpage and grabs the website source code
Then wait for x minutes
Again, HTTP Node crawls the webpage
If Node compares both results are equal if anything is changed. It’ll go to the false branch and notify me in telegram.
