Loading XML document from a url issue

Question

my code :

XmlDocument xml1 = new XmlDocument();
        XmlDocument xml2 = new XmlDocument();
        xml1.Load("http://www.oztivo.net/xmltv/FMDRA_2013-05-31.xml.gz");
        xml2.Load("http://www.oztivo.net/xmltv/GEM-ACT_2013-05-16.xml.gz");

my problem is that on page load for first time everything work great but on the refresh it's giving me an error :

'', hexadecimal value 0x1F, is an invalid character. Line 1, position 1.

Do anyone know how to fix this issue ?

Your URL is for a gzipped version file. You'd need to decompress that first... or remove the .gz part from the URL. — Jon Skeet

You can use HttpWebRequest and the AutomaticDecompression property to automatically decompress the 'gziped' file:

HttpWebRequest request = HttpWebRequest.CreateHttp("http://www.oztivo.net/xmltv/FMDRA_2013-05-31.xml.gz");
request.AutomaticDecompression = DecompressionMethods.GZip;

WebResponse response = request.GetResponse();

XmlDocument xml1 = new XmlDocument();
xml1.Load(response.GetResponseStream());

[Update] Note :

In fact, when testing your urls we can see that they are 'gziped'. If you try to access the urls from a web browser you will see the XML content displayed because the web browser decompress the content.

[Update2] CreateHttp is available from .NET 4 or later. You can do (HttpWebRequest)WebRequest.Create instead if working with .NET < .NET 4
