Question

This is making me feel stupid :-). Say I start at a leaf node, and I traverse up the tree by using .parent(). I need an exit condition once it hits root. At the moment, I’m using parent.@name != “root”, where name is just an attribute, but shouldn’t I be able to check the type of element as well? How? Also, is there another way to end the traversal in as3?

Assuming you are using the XMLNode object:

if (currentNode.parentNode == null)
    // Root

And if you are using the XML object:

if (!xmlNode.parent())
    // Root
