BBC Web API program

[jug]

Hi,

 

I am experimenting with the BBC web API and have come across certain problems.

 

It seems the status code returned from the server response is 0 and also the xml response is null.

Im not totally new to Ajax development but I cant seem to see where the problem lies. The section of code is below.

 

   

function channelsList(){
    req = new XMLHttpRequest();
    req.open("GET", 'http://www0.rdthdo.bbc.co.uk/cgi-perl/api/query.pl?method=bbc.channel.list&format=simple', true);
    req.onreadystatechange = channelsListResponse;
    req.send(null);
}

function channelsListResponse(){

    alert(req.readyState + '-' + req.status + '-' + req.statusText);

  if(req.readyState == 4 && req.status == 200){
        
    var channelsList = req.responseXML.getElementsByTagName('channel');
    alert(channelsList);
  }
}

 

 

Any help would be appreciated.

 

The prototype application can be found at the following URL.

Thanks in advance.
