Extract Text from HTML

Extracting text from HTML is a common task in web development and data processing, aiming to retrieve clean, readable text from HTML code, stripping away all the tags and scripts. This functionality is useful in various scenarios, such as web scraping, content migration, and search engine optimization, where the actual content rather than the markup is of interest.

Historical Background

HTML (HyperText Markup Language) is the standard markup language for documents designed to be displayed in a web browser. Since the early days of the web, there has been a need to extract information from HTML documents, leading to the development of various tools and techniques for parsing HTML and extracting the text content.

Calculation Formula

The process of extracting text from HTML does not involve a mathematical formula but rather parsing and processing the HTML structure to retrieve the text nodes.

Example Calculation

Given an HTML snippet like <p>Hello, <strong>world</strong>!</p>, the extracted text would be Hello, world!.
