URL extractor

A URL extractor is a piece of software or a script that is designed to scan a body of text or a webpage and extract any URLs that it finds. These URLs may be hyperlinks to other webpages, or they may be links to resources such as images or videos. The extracted URLs can then be used for a variety of purposes, such as to create a list of links to be processed later, or to perform some action on each of the URLs, such as downloading the resource or visiting the webpage.
