The scraper

An vital part of each scraper is the data locators (or selectors) which can be used to find the data that you need to extract from the HTML file — usually, XPath, CSS selectors, regex, or a mixture of them is applied.

The web data scraping process

In the event you do it yourself

This is what a common DIY web scraping process looks like:
