C#을 사용하여 XML을 구문 분석하는 방법?

Question

Google의 Geocoding API를 사용하고 있지만 XML을 반환하기 때문에 구문 분석 방법을 모르겠습니다.

나는이처럼 보이는 XML 문서의 위도를 얻으려고 ...

<GeocodeResponse> 
<status>OK</status> 
<result> 
    <type>street_address</type>

내가 어떻게 할 수 있습니까? 이것은 내가 갈 수있는 한도 내입니다.

string baseURL = "https://maps.googleapis.com/maps/api/geocode/xml?"; 
string fullURL = baseURL + "address=" + address + "&sensor=false"; 
Uri ServivrUri = new Uri(fullURL); 
WebClient proxy = new WebClient(); 
byte[] abc = proxy.DownloadData(ServivrUri); 

MemoryStream stream = new MemoryStream(abc); 
XmlDocument xDocument = new XmlDocument(); 
xDocument.Load(stream); 

Answer 1

당신은 그럼 당신은 예를 들어 linqToXml

을 사용할 수 있습니다 대신 XmlDocument

var xDocument = XDocument.Load(stream); 

의 XDocument를 사용해야합니다, 위도를 얻기 위해, 당신은이

var latitude = xDocument.Descendants("geometry").Descendants("location") 
         .First().Element("lat").Value;
