How to iterate over DataGroup List elements ?

Could you implement a version of matchclass that would return the matching

value in 'class' instead returning numeric value (0, 1, ..)?

I would like to know which one of the datagrouplist (or class) elements matches and do some extra manipulations using that information..

--- Here is the doc for findclass ---

findclass

The findclass command searches a data group list for a member that starts with and returns the data-group member string. This is similar to the matchclass command, except that the member is not required to be equal; instead, the member is only required to start with the string and the command returns the entire member value.

The syntax of the findclass command is:

findclass [(separator)]

--------------------------------------

Correct me if I'm wrong, but I guess that in this case I cannot use 'findclass' command because the first argument (string) is 'longer' and the second argument (data group) contains the 'prefixes' that I need to match against.

It seems to me that commands..

     
     set location [HTTP::header "Location"];     
     set matchidx [matchclass $location starts_with $::my_str_class];     
   

..set variable '$matchidx' to index of matching element in my

datagroup list (class).

Is there some way to get the value of element $matchidx from class

or is it possible to make 'matchclass' return the value of matching

element (instead of index). ?

Thanks in advance, Juha
