Regex Tester & Validator

This regex extracts the brand or seller name from Amazon product pages by locating the 'bylineInfo_feature_div' container div, then finding the nested anchor tag with an id starting with 'bylineInfo', and lazily capturing its inner text content. The lazy quantifiers and [\s\S] constructs allow it to span multiple lines of HTML. It's commonly used in web scrapers and price-monitoring tools to pull brand data from e-commerce pages.
