Subject: Tree view hierarchy


Tree view displayed on web page looks like this:

  Smoking
  	Survey & Feedback
  Depression
  	Survey & Feedback
  Stress Management
  	Survey & Feedback
  Weight Management
  	Exercise
  		Survey & Feedback
  	Healthy Eating
  		Survey & Feedback
  	Managing Emotions
  		Survey & Feedback

Using the "className" property of each node, I am able to
determine the hierarchy. After scraping the list of nodes
from the page, I have an array that contains the following:

  [
    [ 1, "Smoking",           "root"   ],
    [ 2, "Survey & Feedback", "leaf"   ],
    [ 3, "Depression",        "root"   ],
    [ 4, "Survey & Feedback", "leaf"   ],
    [ 5, "Stress Management", "root"   ],
    [ 6, "Survey & Feedback", "leaf"   ],
    [ 7, "Weight Management", "root"   ],
    [ 8, "Exercise",          "parent" ],
    [ 9, "Survey & Feedback", "leaf"   ],
    [10, "Healthy Eating",    "parent" ],
    [11, "Survey & Feedback", "leaf"   ],
    [12, "Managing Emotions", "parent" ],
    [13, "Survey & Feedback", "leaf"   ]
  ]

What I need to do is iterate thru each element of the array,
determining the parent and root nodes of each element,
separating each level of the hierarchy with a pipe symbol.
The end result would be an array that contains something
like this:

[
  ["Smoking|Survey & Feedback"]
  ["Depression|Survey & Feedback"]
  ["Stress Management|Survey & Feedback"]
  ["Weight Management|Exercise|Survey & Feedback"],
  ["Weight Management|Healthy Eating|Survey & Feedback"],
  ["Weight Management|Managing Emotions|Survey & Feedback"]
]

Anyone got any ideas on this?

TIA
