Build, test, and debug regular expressions
This regex matches file paths or filenames containing the specific sequence 'NSO', followed by 'HORDIN_XMLDAFNEV', and ending with 'xml'. The '.' characters act as flexible separators, allowing it to catch variations like underscores or dashes. It is typically used with multiline and global flags to filter log entries or directory listings for specific XML files related to a system or project named Dafne.
