[SR-Users] Counting xavp stack

[Alex Balashov]

It would be great if there were some way to count the depth of a stack 
of XAVPs, e.g.

   $xavp(root=>num) = 1;
   $xavp(root[0]=>num) = 2;
   $xavp(root[0]=>num) = 3;
   ...
   $var(depth) = $(xavp(root=>num){avp.count});

Right now, the only way to do this that I know of is something like:

   $var(i) = 0;

   while(defined $xavp(root[$var(i)]=>num))
      $var(i) = $var(i) + 1;

   $var(i) = $var(i) - 1;

Is there a secret I don't know about?
