'Sed' command #4

    Does Bash-online-complier supports control structure as loops and conditional statment ?

    the following command works correctly on my local Unix-based system, but it does not behave as expected in the online compiler!!

    sed -E '/^([0-9]{4}\s*){4}$/{:a /(\*\*\*\*\s+){3}/b; s/((\*\*\*\*\s+)*)?[0-9]+/****/; ta} -'
