The concept of depth-first:

void DF_search(what)
{
  for(each child in what;;child++)
  {
    if(child->hasChilds()) search(child);
  }

  for(each child in what;;child++)
  {
    if(!child->hasChilds()) doSomething();
  }
}

Vice versa, breadth first:
void BF_search(what)
{
  for(each child in what;;child++)
  {
    if(!child->hasChilds()) doSomething();
  }

  for(each child in what;;child++)
  {
    if(child->hasChilds()) search(child);
  }
}
