Extracteur-Web: A Tool for Open Source Intelligence (OSINT)

Extracteur-Web is a powerful tool used in Open Source Intelligence (OSINT) gathering. It's an open-source software that extracts data from the web using a technique called Web Crawling.

Web crawling involves navigating through the web to discover and collect new or updated content. This is done by following hyperlinks on web pages, which allows the tool to access a vast amount of information.

Technical Terms:

• URL (Uniform Resource Locator): The address of a webpage.
• HTML (Hypertext Markup Language): The standard markup language used to create web pages.
• XPATH (XML Path Language): A syntax used to select and extract data from HTML documents.
• DOM (Document Object Model): A representation of the structure of a document, including its elements, attributes, and properties.

Extracteur-Web uses XPATH to select and extract specific data from web pages. It also uses DOM to parse the HTML document and identify relevant information.

How it Works:

The tool starts by sending a request to a webpage, which returns the HTML document. The Extracteur-Web software then parses the HTML using XPATH and DOM, extracting the desired data from the page.

The extracted data is then stored in a database or exported to a file, allowing users to analyze and process the information further.
