[OpenSIPS-Users] Sorting Lists of Data

[Bogdan-Andrei Iancu]

Hi Brett,

There is no such builtin functionality - what we have is for weight-base 
selection (see 
http://www.opensips.org/html/docs/modules/1.6.x/cfgutils.html#id228612).

What I can suggest (as a fast solution) is to implement a bubble-sort 
algh in the script:

    $var(changed) = 1;
    while ( $var(changed)==1 ) {
          $var(i) = 0;
          $var(changed) = 0;
          while ( $(avp(s:price)[$var(i)+1])!=NULL ) {
                if ( $(avp(s:price)[$var(i)]) > $(avp(s:price)[$var(i)+1]) )
                   $var(tmp) = $(avp(s:price)[$var(i)+1]);
                   $(avp(s:price)[$var(i)+1]) = $(avp(s:price)[$var(i)]) ;
                   $(avp(s:price)[$var(i)]) = $var(tmp);
                   $var(changed) = 1;
                 }
                 $var(i) = $var(i) + 1;
          }
    }

haven't tried that so far :P

Regards,
Bogdan
