new XML possible bug

Hi,

I am trying to fetch RSS weather data from BBC Weather - https://weather-broker-cdn.api.bbci.co.uk/en/observation/rss/2643743

I have written a code based on other topic on the forum: https://support.iridiummobile.net/communities/18/topics/13554-create-a-tv-guide-xmltv and I came across the same problem with new XML returning null.

This is my code:

IR.AddListener(IR.EVENT_START,0,function()
{
   BBCWRSS.request(); 
});


var BBCWRSS = {};
BBCWRSS.dev =  IR.CreateDevice(IR.DEVICE_CUSTOM_HTTP_TCP, 'BBCWRSS_dev',
    {Host: "weather-broker-cdn.api.bbci.co.uk",
        Port: 80,
        SSL: false,
        ScriptMode: IR.DIRECT_AND_SCRIPT,
        SendCommandAttempts: 0,
        ConnectWaitTimeMax: 3000,
        ReceiveWaitTimeMax: 5000
    });
    
BBCWRSS.request = function (in_callback){
    BBCWRSS.dev.Connect();
        BBCWRSS.dev.SendEx({
            Type: "GET",
            Url: "/en/observation/rss/2643743",
            cbReceiveText: function (text, code, headers) {
                
                if (code != 200) return;
                var resp = new XML(text);
                IR.Log("RESPONSE TEXT:" +text);
                IR.Log("RESPONSE CODE:" +code);
                IR.Log("RESPONSE HEADERS:" +JSON.Stringify(headers));
                IR.Log("RESPONSE RESP XML:" +resp);
                //BUG: new XML returns null
                BBCWRSS.dev.Disconnect();            
                //in_callback(resp);            
                },
            });
}

Can anyone advise on this?

Thanks!
