XMLParser - NodeList indexes issue

Hi all,

I'm trying to parse (client-side) an XML file, here is the structure:

<?xml version="1.0" encoding="utf-8" ?>
<model xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:noNamespaceSchemaLocation="ModelSchema.xsd"
id="modelId"
extends="models/otherModel.xml">
<name>Model Name</name>
<description>Brief Model description</description>
<characteristic enum="1">
<!-- non relevant child nodes -->
</characteristic>
<characteristic enum="2">
<!-- non relevant child nodes -->
</characteristic>
</model>

I successully parsed the xml file (RequestBuilder, etc...). This is the java code section (relevant part only):

Document modelDocument = XMLParser.parse(.....);

Node root = modelDocument.getElementsByTagName("model").item(0);

NodeList childNodes = root.getChildNodes();

 

 My goal is to get the value of the nodes <name> and <description>, first and second child of the <model> node (known as root, in the java code), but I didn't get what I expected. So I put a set of GWT.log calls, and this is the result:

GWT.log(childNodes.item(0).toString());    // output = ''

GWT.log(childNodes.item(1).toString());    // output = '<name>Model Name</name>'

GWT.log(childNodes.item(2).toString());    // output = ''

GWT.log(childNodes.item(3).toString());    // output = '<description>Brief Model description</description>'

GWT.log(childNodes.item(4).toString());    // output = ''

GWT.log(childNodes.item(5).toString());    // output = '<characteristic enum="1">...</characteristic>'

GWT.log(childNodes.item(6).toString());    // output = ''

GWT.log(childNodes.item(7).toString());     // output = '<characteristic enum="2">...</characteristic>'

 I'm happy I finally got the right values, but I still don't understand why the children nodes correspond only to odd indexes, is such a weird thing. Am I doing something wrong?

Thank you.
