Try something like this:

Put this into a file called parse.awk:

BEGIN {
   FS=" "
}
{
   numstr=$11;
   name=$9;
   i=0;
   pos=index(numstr, "site");
   pos+=4;
   tail=substr(numstr, pos+1);
   num=substr(numstr, pos);
   printf("%c", num);
   while (num ~ /[0-9]+/) {
     i++;
     num=substr(tail, i, 1);
     if (num ~ /[0-9]+/) {
       printf("%c", num);
     }
   }
   printf("\t%s\n", name);
}

Then run this:

ls -la | grep "sitedynamics.com.au" | awk -f parse.awk

That'll do it :)
