Regex Tester & Validator

This regex extracts data from a three-column HTML table row, specifically targeting entries that begin with an 'H' followed by three digits, such as GHS hazard statements (e.g., H302 or H317). It captures the hazard code and the contents of the following two table data cells, skipping over the HTML tags and newlines. It is highly useful for parsing structured HTML data from wiki pages or chemical safety data sheets.
