Build, test, and debug regular expressions
Matches text containing the labels "Birthday" and "Age", capturing the content between them in group 1 and the content after "Age" plus a whitespace in group 2. The flexible \s* tokens allow optional whitespace (including newlines) around the captured segments, making it useful for extracting field values from forms, documents, or log entries. With the global flag enabled, it finds all occurrences throughout the input text.
