The basics of web scraping

The crawler leads the scraper, as if by hand, by the internet, where it extracts the data requested. Study the difference between web crawling & web scraping and how they work.

The crawler

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

The scraper

A web scraper is a specialized software designed to accurately and quickly extract data from a web page. Web scrapers differ widely in design and complicatedity, depending on the project. An essential part of each scraper is the data locators (or selectors) which can be used to seek out the data that you just need to extract from the HTML file – usually, XPath, CSS selectors, regex, or a mixture of them is applied.

The web data scraping process

If you happen to do it yourself

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

Determine the goal website

Collect URLs of the pages the place you wish to extract data from

Make a request to those URLs to get the HTML of the web page

Use locators to find the data within the HTML

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

Simple sufficient, right? It’s! When you just have a small project. But unfortunately, there are quite a few challenges it is advisable tackle when you want data at scale.
