Help loading xml into text fields

programming flash
1

When I test this I get ‘undefined’ in the preview window what did I do wrong ?

xml:


<?xml version="1.0" ?>
<logg>
        <title>My Logg </title>
        <description>How in the hell do I get this inside flash .</description>
    <item>
        <title>My Second Logg post</title>
        <description>A description of my Second Logg post</description>
        </item>
        <item>
        <title>My First logg post</title>
        <description>A description of my First Logg post</description>
        </item>
</logg>

AS:



function loadXML(loaded) {

if (loaded) {

_root.item = this.firstChild.childNodes[0].childNodes[0].firstChild.nodeValue;
_root.description = this.firstChild.childNodes[0].childNodes[1].firstChild.nodeValue;
title_txt.text = _root.item;
description_txt.text = _root.description;
} else {
trace("file not loaded!");
  }
}
xmlData = new XML();
xmlData.ignoreWhite = true;
xmlData.onLoad = loadXML;
xmlData.load("my_logg.xml");
