An necessary part of every scraper is the data locators (or selectors) which are used to seek out 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
If you happen to do it yourself
This is what a basic DIY web scraping process looks like:

Identify the target website
Gather URLs of the pages the place you want to extract data from
Make a request to those URLs to get the HTML of the page

Simple sufficient, proper? It's! In the event you just have a small project. However unfortunately, there are quite just a few challenges you want to tackle if you happen to need data at scale.
