Cant read a part of xml file using AS3

Question

Hi
i can read everything from my xml file except a part that i can always get teh first items of each category (it will make more sence in a sec)
So here is my xml
[HTML]<?xml version="1.0" encoding="UTF-8"?>
<flashxml>
  <second_page>
    <sp text="ss ptextj"/>
    <ss text="sptext"/>
    <clas text="clas"/>
  </second_page>
  <third_page>
    <ss>
      <category name="categor">
        <item>3333</item>
        <item>H4444</item>
        <item>etc etc etc </item>
      </category>
      <category name="security ">
        <item>SSL</item>
        <item>Hacke</item>
        <item>etc etc etc </item>
      </category>
    </ss>
    <sp>
      <category name="security a">
        <item>SSL lallalala</item>
        <item>Hacker</item>
        <item>etc etc etc </item>
      </category>
      <category name="onlin">
        <item>Hussle free</item>
        <item>Diafore</item>
        <item>etc etc 2 </item>
      </category>
    </sp>
    <classifieds>
      <category name="Best">
        <item>Additem1</item>
        <item>Additem2</item>
        <item>Additem3 </item>
      </category>
    </classifieds>
  </third_page>
</flashxml>[/HTML]
I am trying for each category in the xml to get the relevant items ...
The problem is that if i try to read for e.g the second set of items for the second category of <sp> using a counter it throws a type error
TypeError: Error #1010: A term is undefined and has no properties.
at MethodInfo-1()
at flash.events::EventDispatcher/flash.events:EventDispatcher::dispatchEventFunction()
at flash.events::EventDispatcher/dispatchEvent()
at flash.net::URLLoader/flash.net:URLLoader::onComplete()
so the following works
var itemslist:XMLList = xml.third_page.ss.category[0].item;  (it will always display the first items of the first category for all the categories
so for instance for sp will always return even for the second category
<item>SSL lallalala</item>
        <item>Hacker</item>
        <item>etc etc etc </item>
but when i am using
var itemslist:XMLList = xml.third_page.ss.category[i].item;
i am getting the type error above TypeError: Error #1010 .. (no idea why)
Any help will be much appreciated

Answer 1

use
var itemslist:XMLList = captionElement.item;
instead of
var itemslist:XMLList = xml.third_page.sp.category[0].item;
that should work. You already got the category node in your captionElement variable, why not just use it instead of looking it up again in the document tree?
