I need some help with taking the array "pcor_sections" and exactly creating the "TREE_NODES" array. I am new to JS and you seriously don't want me to paste what I have so far. It's confusing.
Some rules are posted at the bottom to make it easier to understand.


var pcor_sections = [ 0

,'<p class="chap"><a href="chf-ES.htm#P6_36" target="_top">Executive Summary</a></p>'

,'<p class="ahead"><a href="chf-ES-cmc-00.htm#P52_1438" target="_top">What are the key parameters of the CHF market?</a></p>'

,'<p class="chap"><a href="Pharmacor-Chapter-Head.htm#P89_11313" target="_top">Introduction</a></p>'

Rules
remove #p242_2393 framgments where the classes = chap or ahead.
if a chap has no ahead or bhead following it then we need to add {format:{isFolder:true}} (see introduction)
Also, notice the brakets ] and when they should or shouldn't close. Like if Ahead has B head you keep the Ahead open and close after bhead.
