Server Side XML Class

Question

Hi,
Everything I read in from my XML is of nodeType Element. I am trying to extract  the data. However because the type coming back is of type 1 (Element) I am unable to use nodeValue. What am I doing wrong? I wish to extract the directory and server information.
This is my XML
<?xml version="1.0" encoding="UTF-8"?>
<mainlist version="1" xmlns="http://xspf.org/ns/0/">
          <subList>
                    <id>
                              <title></title>
                              <creator></creator>
                              <directory>dir_data_here</directory>
                              <meta rel="server">server_info_here</meta>
                              <meta rel="version">version_here</meta>
          </id>
          </subList>
</mainlist>
This is my code:
     // Create a new XML object.
     var flooring = new XML();
     //load in the external xml data
     flooring.load("data.xml");
     // Set the ignoreWhite property to true (the default value is false).
     flooring.ignoreWhite = true;
     // After loading is complete, trace the XML object.
     flooring.onLoad = function(success) {
          //trace(flooring);
          trace( flooring.childNodes[0].childNodes[0].childNodes[0].parentNode);
          trace( flooring.childNodes[0].childNodes[0].childNodes[0].nodeValue);
          trace( flooring.childNodes[0].childNodes[0].childNodes[0].nodeType);
          trace( flooring.childNodes[0].childNodes[0].childNodes[0].nodeName);
          trace(flooring.childNodes[0].childNodes[0].childNodes[0].toString());

Many thanks.

Answer 1

In fact my actual code was pulling XML from a HTTP server, like the code below.
var flooring = new XML();
flooring.onLoad = function(success) {
     do some stuff
     do some stuff
flooring.load(HTTP_SERVER);
Your comment does not explain why the tags are elements and not text type. It does not matter as I have solved it another way using attributes and I decided to pull in a SMIL file rather than XML.
