Hi,

I'm trying to do dynamic sorting on an array, based on command line options, e.g.: I have an option '--sortBy' which can specify multiple 'attributes' and then you can specify ascending or descending, etc has (a) or (d) or defaults to ascending (a).

e.g. --sortBy='backupNextDateTime,backupNumber(d)'

I have an xml config which tells me if the values are strings, integers or other data types.

I would like to know:

Is it possible to specify the 'sort criteria' as a 'string'?

I've managed to get the sort criteria built -

e.g.: $buildString = '{ $b->[11] <=> $a->[11] || $a->[9] <=> $b->[9] }'

is there a way I can do something like:

@sorted = sort $buildString @origionalArray

or is there another way. I've seen the subroutine use but that seems not the way to go as I have to dynamically create the 'filter' criteria.

Any help would be greatly appreciated.

Thanks

Frank
