In lots of projects, you first “crawl” the web or one particular website to discover URLs which then you definitely pass on to your scraper.

The scraper

A web scraper is a specialised instrument designed to accurately and quickly extract data from a web page. Web scrapers range widely in design and complexity, depending on the project. An necessary part of every scraper is the data locators (or selectors) that are used to search out the data that you simply want to extract from the HTML file – often, XPath, CSS selectors, regex, or a combination of them is applied.

The web data scraping process

For those who do it your self

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

Establish the goal website

Gather URLs of the pages where you need to extract data from

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

Use locators to find the data in the HTML

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

Simple sufficient, right? It’s! If you just have a small project. However sadly, there are quite a couple of challenges it’s worthwhile to tackle for those who want data at scale.
