xslt가 예상대로 작동하지 않고 일치하는 변수가

Question

수정 메시지를 처리하기 위해 xslt에서 작업하고 있습니다. (이미이 문제를 해결했습니다.) 참조 된 모든 필드를 유지하려고합니다. 다양한 방법. 내 XSLT는이 일을 처리하지 못하고 있으며 이유를 찾기가 매우 힘들다. 나는 필드를 유지하는 xslt를 줄 였지만 전체 xslt는 유지하지 않습니다. 이것은 변수가 작동하는 방식에 대한 나의 이해가 부족하기 때문일 수 있지만 확실하지는 않습니다. 나는 xslt 프로그래머가 아니기 때문에 이것을 매우 어렵게 생각하고있다. XML 출력을 생성 (는 바하 필드를 유지하기 위해 관리와 같이)

샘플 XML 파일은

<fix> 
<messages> 
    <message name="TheReport" > 
     <component name="OuterComp" required="N" /> 
    </message> 
</messages> 
<components> 
    <component name="OuterComp"> 
     <field name="AppID" required="N" /> 
     <component name="InnerComp" required="N" /> 
    </component> 
    <component name="InnerComp"> 
     <group name="Bah" required="N" > 
      <field name="NewField" required="N" /> 
     </group> 
    </component> 
</components> 
<fields> 
    <field number="3" name="AppID" type="STRING" /> 
    <field number="15" name="Bah" type="STRING" /> 
    <field number="16" name="NewField" type="STRING" /> 
</fields> 
</fix>

무엇이 잘못 되었나요?

감사합니다.

Eclipse XSLT 디버거 사용법을 관리하고이 문제를 분류했습니다. 내가 예상하지 못한 길을 택하고 있었다.
