The crawler<\/p>\n
A web crawler, which we generally call a “spider,” is an artificial intelligence that browses the internet to index and seek for content material by following links and exploring, like a person with too much time on their hands. In many projects, you first “crawl” the web or one specific website to discover URLs which you then pass on to your scraper.<\/p>\n
The scraper<\/p>\n
A web scraper is a specialized device designed to accurately and quickly extract data from a web page. Web scrapers vary widely in design and complexity, depending on the project. An essential part of each scraper is the data locators (or selectors) which might be used to find the data that you need to extract from the HTML file – usually, XPath, CSS selectors, regex, or a mixture of them is applied.<\/p>\n
