> Give an outline item, I need to walk through all its children. ??The items at each level of the hierarchy form a linked list, chained together through their Prev and Next entries and accessed through the First and Last entries in the parent item?? so I created a simple patch to allow this kind of code:
> {code}
> if(node !=null){
>        for (PDOutlineItem current : node.children()) {
>                 //do something with the            
>        }
> }
> {code}
> Given an item, PDOutlineNode.children returns an iterator that walks through the children until there is no NEXT or NEXT is equals to the starting element.
