Regex Editor & Tester

This regular expression captures a specific block of text from a document, starting with a check number and ending with a payment date. It looks for the string "Check_Number:" followed by digits, then lazily matches until it finds a title attribute containing at least six digits. Finally, it matches further until it finds "Payment Date" followed by a date in DD/MM/YYYY format. It is highly useful for extracting structured payment information from HTML or text-based invoices and financial reports.
