xmldom getAttribute firefox problem

[jphaycock]

Hi all

I am trying to get a url attribute from an xml node:
<item>
<media url="http://blablabla.com" />
</item>

I can do this in IE with the following code:
var newDom = xmlhttp.respons eXML;
var x = newDom.getEleme ntsByTagName("i tem");
var urlNode = x[0].getElementsByT agName('media') ;
var myUrl = urlNode[0].getAttribute(' url');

If I try this code in FireFox it gives me the following error:

urlNode[0] has no properties referring to this line : myUrl =
urlNode[0].getAttribute(' url');

I've tried to fix it lots of ways with no joy.

Any help is much appreciated

Thanks in advance

John

Firebug (1.05) test case

var s = [
'<item>',
'<media url="http://blablabla.com" />',
'</item>'
].join("\n");

try
{
var p = new DOMParser();
var newDom = p.parseFromStri ng(s, "text/xml");
var x = newDom.getEleme ntsByTagName("i tem");
var urlNode = x[0].getElementsByT agName("media") ;
var myUrl = urlNode[0].getAttribute(" url");
myUrl
}

Either you are doing something else wrong or an extension interferes.

Thank you Thomas. You are right

A colleague has established that it is the way the xml is delivered/
formated that is causing problems

ACK. Probably you have not served it with an XML MIME media type.

What I found most interesting when creating the test case is that Firebug
now appears to have E4X support built-in which is why

var s =
<item>
<media url="http://blablabla.com" />
</item>;

works there, too. (For DOMParser::pars eFromString(), implicit conversion
from type `xml' to type `string' then takes place.)
