Regex Tester & Validator

Parses structured strings delimited by literal 'head-' and 'tail' markers, capturing optional Cyrillic labels 'Бренд' (Brand) and 'Артикул' (Article/SKU) into named groups, along with the text segments between them. Uses possessive quantifiers (?+, *+) and tempered dot (?:(?!...).)*+ to efficiently split content at known markers without backtracking. Ideal for extracting brand names and product codes from e-commerce product titles, SKU strings, or marketplace listing data.
