Update on my test. This works perfectly Robert - thank you very much! But there is one small problem that I am trouble-shooting: it only goes one layer and doesn't progress any further. I suspect it is on this section of code that I am going to add some stuff to to see what is happening.

if( !($parents = &$children) ){
           break;
       }
