[Michael Wilde]

This example may be helpful:

$ cat -n regexpmap.swift
      1    type file;
      2
      3    string fnames[] = [
      4    "/data/dir/000001/f01.dat",
      5    "/data/dir/000001/f02.dat",
      6    "/data/dir/000002/f03.dat",
      7    "/data/dir/000002/f04.dat",
      8    "/data/dir/000003/f05.dat",
      9    "/data/dir/000003/f06.dat"];
     10
     11    file data[]<array_mapper; files=fnames>;
     12
     13    file image[] <structured_regexp_mapper;
     14      source=data,
     15      match="(/data/dir/[0-9][0-9]*/.*?)dat$",
     16      transform="\\1img">;
     17
     18    iterate i {
     19      tracef(" data[%i] = %s\nimage[%i] = %s\n",
     20             i, filename(data[i]),
     21             i, filename(image[i]));
     22    } until (i==6);
