So I hate to ask this but the last 10 hours of searching and attempting to code have turned up nothing.
I have a visual studio project with an SQL database attached. I
Here is how you can parse the response using Linq to XML
Live Example: http://balexandre.com/stackoverflow/7789623/
The link also include the source code, but the parsing using Linq to XML is quick easy, fun and extremely simple:
private GoogleWheatherInfo parseGoogleWeatherResponse(string url)
{
    GoogleWheatherInfo gw = new GoogleWheatherInfo();
    // get the XML
    XDocument doc = XDocument.Load(url);
    // parse data
    gw.ForecastInformation = (from x in doc.Descendants("forecast_information")
                              select new GWForecastInfo
                              {
                                  City = x.Descendants("city").First().Attribute("data").Value,
                                  PostalCode = x.Descendants("postal_code").First().Attribute("data").Value,
                                  Latitude = long.Parse(string.IsNullOrEmpty(x.Descendants("latitude_e6").First().Attribute("data").Value) ? "0" : x.Descendants("latitude_e6").First().Attribute("data").Value),
                                  Longitude = long.Parse(string.IsNullOrEmpty(x.Descendants("longitude_e6").First().Attribute("data").Value) ? "0" : x.Descendants("longitude_e6").First().Attribute("data").Value),
                                  ForecastDate = DateTime.ParseExact(x.Descendants("forecast_date").First().Attribute("data").Value, "yyyy-MM-dd", CultureInfo.InvariantCulture),
                                  CurrentDate = DateTime.ParseExact(x.Descendants("current_date_time").First().Attribute("data").Value, "yyyy-MM-dd HH:mm:ss K", CultureInfo.InvariantCulture),
                                  UnitSystem = x.Descendants("unit_system").First().Attribute("data").Value
                              }).Single();
    gw.CurrentCondition = (from x in doc.Descendants("current_conditions")
                           select new GWCurrentCondition
                           {
                               Condition = x.Descendants("condition").First().Attribute("data").Value,
                               TemperatureC = long.Parse(x.Descendants("temp_c").First().Attribute("data").Value),
                               TemperatureF = long.Parse(x.Descendants("temp_f").First().Attribute("data").Value),
                               Humidity = x.Descendants("humidity").First().Attribute("data").Value,
                               Image = x.Descendants("icon").First().Attribute("data").Value,
                               Wind = x.Descendants("wind_condition").First().Attribute("data").Value
                           }).Single();
    gw.ForecastConditions = (from x in doc.Descendants("forecast_conditions")
                             select new GWForecastCondition
                             {
                                 DayOfWeek = x.Descendants("day_of_week").First().Attribute("data").Value,
                                 Low = double.Parse(x.Descendants("low").First().Attribute("data").Value),
                                 High = double.Parse(x.Descendants("high").First().Attribute("data").Value),
                                 Image = x.Descendants("icon").First().Attribute("data").Value,
                                 Condition = x.Descendants("condition").First().Attribute("data").Value,
                             }).ToList();
    return gw;
}
I hope this gives you some knowledge on how easy is to parse any XML document.
