  xmlNodePtr current, child;

  current = ....
  child = current->children;
  while (child != NULL) {
     /* handle child, especially looking at child->type first */

     child = child->next;
  }

I'm not sure adding a function would be any cleaner, one would need to
allocate the memory for the array, let the user free it (dangerous or
one need to handle the case where the caller allocate the array but
this may be too small ...). Iterating on an array is only barely simpler
the only distinctive advantage would be random access.
