The fundamentals of web scraping
It’s very simple, in truth, and works by way of parts: a web crawler and a web scraper. The web crawler is the horse, and the scraper is the chariot. The crawler leads the scraper, as if by hand, via the internet, where it extracts the data requested. Be taught the difference between web crawling & web scraping and how they work.
The crawler
A web crawler, which we typically call a “spider,” is an artificial intelligence that browses the internet to index and search for content material by following links and exploring, like an individual with too much time on their hands. In many projects, you first “crawl” the web or one specific website to discover URLs which then you pass on to your scraper.
The scraper
A web scraper is a specialized tool designed to accurately and quickly extract data from a web page. Web scrapers fluctuate widely in design and complicatedity, depending on the project. An vital part of every scraper is the data locators (or selectors) which might be used to search out the data that you simply need to extract from the HTML file – normally, XPath, CSS selectors, regex, or a combination of them is applied.
The web data scraping process
In case you do it yourself
This is what a general DIY web scraping process looks like:
Identify the target website
Collect URLs of the pages where you want to extract data from
Make a request to these URLs to get the HTML of the web page
Use locators to seek out the data in the HTML
Save the data in a JSON or CSV file or some other structured format
Simple enough, proper? It is! If you just have a small project. But sadly, there are quite a number of challenges it’s good to tackle if you need data at scale. For example, sustaining the scraper if the website format modifications, managing proxies, executing javascript, or working round antibots. These are all deeply technical problems that can eat up plenty of resources. That’s part of the reason many companies select to outsource their web data projects.
