A few optimizations for general coding practice:
uint is slower than int for math and should only be used if you're not doing
math on it. Number is faster than uint for numbers higher than int's positive
limit. Generally speaking, always use int in for/while loops.
There's no need to call p.parent() twice each loop. You can shortcut this by
setting p to its parent in the condition check.
Pre-increment is faster than post-increment.
Searching for a Boolean resolve instead of a specific value is faster.
var p:XML = myNode;
var depth:int;
while (p = p.parent())
{
++depth;
}

If you have a node, you can count its depth using one of two methods
calling a recursive function or simply doing something like this:
var p:XML = myNode;
var depth:uint = 0;
while (p.parent() != undefined)
{
depth++;
p = p.parent();
}
// depth here would be the number of parent.
if you only want to count parents where parent().name() == "person" then change
the while statement to read:
while ((p.parent() != undefined)&& (p.parent().name() == "person"))
{
depth++;
p = p.parent();
}

Subject: [Flashcoders] xml: counting parents
I am still trying to find a way to see where a child is within the xml - on
what level... is it possible to count a nodes parents?
So if I had:
<person att="1">
<person att="2">
<person att="3"/>
<person att="4"/>
</person>
</person>
1 would return that it has 0 parents, 2 would say it has 1 parent, 3& 4 would
say they have 2 parents....
hope that makes sense....
Ted
