Hi Steven, If you are using XML, then by all means use Tracey's example. I am building something similar, but I am using objects in an ArrayCollection instead of XML. What I have done is add an "id" and "parent" field to my object. When I am building my ArrayCollection of objects, I make sure to assign the "parent" field to the correct "id" value.
Walking up the tree from a low level is simple. Just recursively (or in a while loop) find the next parent until the parent field is null.
