The data flow getting failure in this line
xmlError = doc.parseError();
if(xmlError && xmlError.errorCode() != 0)
{
throw error(strFmt("XML Error: %1", xmlError.reason()));
}
May I know what might me the reason? am fetching the data from web URL.
Here is the full code.

request = System.Net.WebRequest::Create(url) as System.Net.HttpWebRequest;
// If required by the server, set the credentials.
//request.Credentials = CredentialCache.DefaultCredentials;
webResponse = request.GetResponse();
