XML : Reading data from XML file in C#

I am attempting to read data from an XML file in C# (for Windows Phone). I return the following XML file:

  private async void GetCoords2()      {          string requestURI = "https://maps.googleapis.com/maps/api/geocode/xml?address=Donegal%20Town&key=XXX";            HttpWebRequest request = HttpWebRequest.Create(requestURI) as HttpWebRequest;          WebResponse response = await request.GetResponseAsync();          using (var reader = new StreamReader(response.GetResponseStream()))          {              responseContent = reader.ReadToEnd();              // Do anything with you content. Convert it to xml, json or anything.                ParseContent();          }      }    

I am attempting to retrieve the first instance of latitude and longtitude from the XML file, which is available here: https://maps.googleapis.com/maps/api/geocode/xml?address=Donegal%20Town&key=XXX

I have followed several samples from online, and previous projects I have worked on, but none seem to be working.

How can I retrieve the first instance of lat and lon?

Thanks.

Edit: had to remove key from URL, posted screenshot of image instead.

The XML file

UPDATE: The code I currently have.

  void ParseContent()      {          XmlReader xmlReader = XmlReader.Create(responseContent);          List<string> aTitle = new List<string>();            // Add as many as attributes you have in your "stop" element            XmlReader reader = XmlReader.Create(responseContent);          reader.ReadToDescendant("location");          while (reader.Read())          {              reader.MoveToFirstAttribute();                reader.ReadToFollowing("lat");              string latX = reader.ReadElementContentAsString();                reader.ReadToFollowing("lng");              string lngX = reader.ReadElementContentAsString();                //reader.ReadToFollowing("Subcategory");              //string subcategory = reader.ReadElementContentAsString();                //reader.ReadToFollowing("Favourited");              //Boolean favourited = Boolean.Parse(reader.ReadElementContentAsString());                //basketxml.Add(new Pets(name, category, subcategory, description, dob, stock, price, image, id, favourited));                MessageBox.Show(latX + " / " + lngX);          }      }
