Regex Tester & Validator

This regex matches HTML tags (<.*?>), HTML entities (&.*?;), newline characters (\n), non-breaking spaces (\xa0), and URLs starting with http:// or https:// that are followed by a double quote. It is used to clean and preprocess raw HTML content by removing markup, entities, whitespace artifacts, and hyperlink references, making the text suitable for NLP or data extraction tasks.
