Regex Tester & Validator

This regular expression is designed to extract plain text content from within an HTML table data cell (`<td>`). It works by matching the opening `<td>` tag and its attributes, then skipping over any simple inline HTML tags (like `<b>` or `<span>`) to capture the underlying text in the first capturing group. It is useful for basic web scraping or data extraction tasks where you need the visible text from table columns rather than the raw HTML markup.
