The scraper

An vital part of every scraper is the data locators (or selectors) which are used to find the data that you just wish to extract from the HTML file — usually, XPath, CSS selectors, regex, or a mix of them is applied.

The web data scraping process

In case you do it yourself

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

Identify the target website

Acquire URLs of the pages the place you need to extract data from

Make a request to these URLs to get the HTML of the page

Use locators to search out the data within the HTML

Save the data in a JSON or CSV file or some other structured format

Simple sufficient, proper? It is! In case you just have a small project. But sadly, there are quite just a few challenges that you must tackle should you want data at scale.
