I am getting crazy. Can't access XML contents in Firefox.

Hello sirs,

I am trying to send a POST request to a webservice on the click of a
button. This will return me an XML document with a list of combo box
items.

The problem: in FIREFOX, when the get the XmlDocument from the
XmlHttpRequest object, I can't access its contents. I keep getting
empty strings and "null".

This is my code:

---

function GetComboBoxItems(p_strType, p_strCode)
{
var objParameters =3D new Array();
objParameters[0] =3D p_strType;
objParameters[1] =3D p_strCode;

var objHttpRequest =3D

SendRequest("/MeuWebService/MyWebService.asmx/GetComboBoxIte=ADms",
objParameters);

alert(objHttpRequest.responseT=ADext); // alerts the XML doc
(see below)

/*

this is the XML document:

<?xml version=3D"1.0" enconding=3D"utf-8"?>
<ReturnDocument>
<ComboItem>
<Key>1</Key>
<Description>My first item</Description>
</ComboItem>
<ComboItem>
<Key>2</Key>
<Description>My second item</Description>
</ComboItem>
</ReturnDocument>

*/

alert(objHttpRequest.responseX=ADML); // alerts '[object
XMLDocument]'

var XmlDoc =3D objHttpRequest.responseXML;

var arrTemp =3D
XmlDoc.documentElement.getElem=ADentsByTagName("ComboItem");

alert(arrTemp.length); // alerts '2'

// show contents (Firefox)
for(var i =3D 0; i < arrTemp.length; i++)
{
alert(arrTemp[i].childNodes[0]=AD.nodeValue); // alerts empty
string
alert(arrTemp[i].childNodes[1]=AD.nodeValue); // alerts
'null'
}

/*
// show contents (IE) - works perfectly
for(var i =3D 0; i < arrTemp.length; i++)
{
alert(arrTemp[i].childNodes[0]=AD.text);
alert(arrTemp[i].childNodes[1]=AD.text);
alert(arrTemp[i].childNodes[2]=AD.text);
} */

}

---

I searched everywhere for a logic explanation, but couldn't find any.

In IE it works perfectly. What am I doing wrong?=20

TIA,=20

The first child is the blank space between the <ComboItem> and the
<Key>. The second child is a <Key> element and elements have a nodeValue
of null.

For example:

for(var i = 0; i < arrTemp.length; i++) {
alert(arrTemp[i].childNodes[0]_.firstChild.data);
}

is what your looking, when debugging it's a good idea to check

arrTemp[i].childNodes[0]_.nodeType = 1 (it's an element)
