XSLT 정렬 및 요소에 따라 중복을 제거하고

Question

당신은 내가 강타하고 내 XSLT 좀 도와 주시겠습니까 속성,

요구 사항 : 내 XML에서 제공의 모든 레코드/SKU가 동일하고, 제공/고객 -attributes/custom-attribute/Feed_SKU가 강하면 그 레코드를 유지해야합니다 (이것은 최신 레코드이고 다른 하나는 무시합니다).

내 케이스 Feed_SKU = 09/07/2014 23:21:20이 최신 기록입니다.

저는 xsl : key를 사용하여 비교하고 속성 값 (Feed_SKU)을 분석하는 데 약간의 어려움을 겪었습니다. 여기 좀 도와주세요.

Answer 1

은이 문제에 대한 두 부분이 있습니다 (작동하지 않음) 함께 같은 sku을 공유하는 이벤트를 그룹화하고 두 번째로 각 그룹 내의 최신 날짜를 찾습니다. 첫 번째 부분에서는 Muenchian 그룹화를 사용할 수 있습니다. 두 번째로 문자열 조작을 통해 창의력을 발휘해야합니다. XSLT 1.0에는 날짜와 시간에 대한 특별한 지원이 없으므로 타임 스탬프 값을 연대순으로 일치하는 형식으로 마사지해야합니다 사전 편집 순서.

내가 타임 스탬프가이 질문에 질문을 받았다 9 월, 2014 년 7 날짜 이후가 될 것이기 때문이다/월/년을 dd는되지만 가정 한 그들이 실제로 있다면 mm/DD/YYYY 다음 ' 두 번째 및 세 번째 substring 호출을 바꿔 주문해야합니다.
