- **URL Parsing Patterns**: Extract URL components (protocol, domain, path, query, fragment) from URLs
- **Email Parsing Patterns**: Extract email components (local part, domain, TLD) from email addresses
- **Log File Parsing Patterns**: Parse server log entries with timestamp, level, message, and metadata
- **IP Address Parsing Patterns**: Extract IP address octets and components from IPv4 addresses
- **GPS Coordinates Parsing Patterns**: Extract latitude and longitude from GPS coordinate formats
- **Product Code Parsing Patterns**: Extract product information from SKU, UPC, and product codes
- **File Path Parsing Patterns**: Extract directory, filename, and extension from file paths
- **Person Name Parsing Patterns**: Parse person names into title, first name, middle name, last name, and suffix
