I would use $regex.split() for that:

    // $regex.split(<val>, <pat>, <fmt>[, <flags>])
    //
    // Split a value of an arbitrary type into a list of unmatched value parts
    // and replacements of the matched parts, omitting empty ones. Convert the
    // value to string prior to matching.
    //
    // Substitution escape sequences are extended with a subset of Perl
    // sequences (see libbutl/regex.mxx for details).
    //
    // The following flags are supported:
    //
    // icase             - match ignoring case
    //
    // format_no_copy    - do not copy unmatched value parts into the result
    //

Here is an example:
