값을 검색하기 위해 XmlDocument.SelectNodes를 가져올 수 없습니다?

C# 코드 :

XmlDocument xdcDocument = new XmlDocument(); 

xdcDocument.Load(@"E:\\Hotel.xml"); 

XmlElement xelRoot = xdcDocument.DocumentElement; 
XmlNodeList listOfContacts = xdcDocument.SelectNodes("/HotelValuedAvailRS/ServiceHotel/HotelInfo"); 
foreach (XmlNode xndNode in listOfContacts) 
{ 
    string name = xndNode["Name"].InnerText; 
    string order = xndNode["Order"].InnerText; 
} 

내가 위의 코드와 위의 XML에서 모든 세부 사항을 받고 있지 않다. 도와주세요.

Answer 1

listOfContacts을 (를) 선택하는 데 사용하는 xpath가 문서의 내용과 일치하지 않습니다. 관심있는 노드의 실제 경로를 지정하도록 변경하십시오.

사실 루프 내에서 요소 이름을 지정하지 마십시오. 문서의 어느 노드에서 일치시킬 것으로 예상 했습니까?

편집 # 1 : 사실 이제는 전체 문서를 지정 했으므로 더 적절합니다. 컴파일하고 실행해야했지만 xpath에 네임 스페이스 선언이 없습니다. 루트 요소가 네임 스페이스 http://www.hotelbeds.com/schemas/2005/06/messages에 있다고 선언했지만 xpath는 네임 스페이스가없는 요소 만 선택했습니다.

이 문제를 해결하는 가장 쉬운 방법은 XPath에있는 모든 요소 이름 앞에 접두어를 사용하는 것이다

"/ns:HotelValuedAvailRS/ns:ServiceHotel/ns:HotelInfo"

그리고 SelectNodes에 통화에 정의 된이 접두어 함께 XmlNamespaceManager 통과.
