데이터베이스에서 가져온 값을 요소 이름으로 사용하여 생성 된 XML의 요소 및/또는 속성의 이름을 바꾸는 방법을 알아야합니다.XmlAttributeOverrides를 사용하여 객체 트리의 요소 이름 변경

내 개체 예를 들어

, 여기에 내 현재 프로세스에서 잠재적 인 XML 출력입니다

잘하면 분명 하듯이 "Medication"또는 "User"라는 객체 유형이 없기 때문에 이것들을 유추해야합니다. f ROM 데이터. 그래서 데이터의 값을 사용하여 요소 이름을 변경하는 방법을 알아야하지만 각 요소 이름이 연관된 EntityDefinitionName을 기반으로 변경되도록 개체 트리를 크롤링하는 방법을 알아야합니다. 직렬화 이전에 객체 트리를 채우기 위해 재귀를 사용하고 있습니다. 나는 다음과 같은 코드 내 XmlRoot 이름을 변경하기 위해 노력 알고

XmlAttributeOverrides xmlOverrides = new XmlAttributeOverrides(); 
XmlAttributes attribs = new XmlAttributes(); 
XmlRootAttribute rootAttr = new XmlRootAttribute(); 
rootAttr.ElementName = collection.Find(e => e.Level == 1).EntityDefinitionName.Replace(" ", ""); 
attribs.XmlRoot = rootAttr;

을하지만 그 요소 또는 노드와 관련된 EntityDefinitionName에 따라 각 요소의 이름을 변경하는 방법을 알아낼 필요가있다.

미리 감사드립니다.

사용자 지정 직렬화를 사용하면 XSLT 스타일 시트를 사용하여 질문을 해결하는 다른 방법을 제시 할 수 있습니다.

var xml = File.Open("input.xml", FileMode.Open); // or any stream 
var xslTrans = new XslCompiledTransform(); 
xslTrans.Load(XmlReader.Create(File.Open("yourxslfile.xlst", FileMode.Open))); 
var output = File.Create("output.xml"); // or a stream 
var xw = XmlWriter.Create(output); 
xslTrans.Transform(XmlReader.Create(xml), xw); 
xw.Close();
