xsl 변수를 사용하여 업데이트해야하는 레코드의 하위 ID를 얻는 방법은 무엇입니까?

Question

csharp 및 xslt를 사용하여 중첩 된 레코드를 업데이트하려고합니다.

는 XML 데이터입니다 : 각 여기 TopicAnalysisbyTopicAnalysisID 내 XSLT 코드에 대해 나는 TopicAnswerID 얻을 수 있도록하려면

Answer 1

약간의 작업을 수행하기가 어려우며 게시 된 코드에 몇 가지 문제가 있습니다. 가장 중요한 것은 처리의 성격이며, 모두 하나의 큰 루트 섹션에있는 것처럼 보입니다. 종종 항목을 반복하는 경우에는 요소를 샅샅이 뒤지고 요소의 컨텍스트를 선택하고 그 값을 다른 곳에서 찾는 변수를 만드는 등의 작업을 수행합니다. 그러나, 나는이 식별자가 무엇이고 해야할지 이해하는 데 어려움을 겪고 있습니다. 예를 들어, 당신은 가지고 있습니다;

<input type="hidden" id="hiTopicID" name="hiTopicID" 
      value="{/root/BaseInfo/QueryData/TopicID}" /> 

그러나 경로 '/ 루트/BaseInfo/QueryData/한 TopicID'하지 확신 찾는 무엇을하지 무엇을, 당신의 XML 입력 파일에 존재한다.

그러나 내가 겪고있는 것으로 의심되는 것은 다음과 같습니다.

<!-- First, just a simple variable as a shortcut for a long path --> 
<xsl:variable name="lut" select="/root/BaseInfo/QueryData/TopicID" /> 

<!-- Then, use it for finding a section with a sub-element of that value --> 
<xsl:value-of select="/root/TopicAnalysisbyTopicAnalysisID[TopicID=$lut]/TopicDescription" /> 

이

나는 여전히 불분명 생각 (당신이 후있어 무엇 이건 TopicDescription 교체), 그리고 당신이 XML 데이터와 당신을 원조하지 않는 XSLT 코드의 컨텍스트를 설정 한 방법 의심 이것에 대해 최선의 방법을 이해하는 것. Using ...는 흐름이 잘 작동하고 지나치게 복잡한 입력 XML에서 허덕이는 일이 없도록하는 가장 좋은 방법입니다.

건배. :)
