XML과 Schematron을 사용하여 날짜를 비교하는 방법

Question

Schematron XML 날짜 비교가 작동하지 않습니다. 그리고 그것은 잘못된 오류를 반환합니다. 나는 schematron 1.01을 사용하고 있다고 생각한다. 나는 MSDN에서 C# 및 DLL을 사용하고 있습니다 :

From pattern "Check co-occurrence constraints" 
    Assert fails: VisitDate must be within a valid date range as specified in dataBeginDate and dataEndDate 
    At: /MyData[1]/Site[1]/Patient[1]/form_Baseline[1]/dat_VisitDate[1] 
     <dat_VisitDate signedWho="System" value="2009-02-02">...</dat_VisitDate> 
     (Line: 7, Column: 10) 

스키마 트론 규칙 :

<sch:rule context="MyData/Site/Patient/form_Baseline/dat_VisitDate"> 
    <sch:assert test="@value > //MyData/@dataBeginDate">VisitDate must be within a valid date range as specified in dataBeginDate and dataEndDate</sch:assert> 
</sch:rule>

Answer 1

찾을 답 : 1.0은 비교 연산자를 숫자 < 및 >를 사용

의 XPath. 따라서 날짜를 숫자 값으로 변환해야합니다.

<sch:assert test="translate(@value, '-', '') > translate(//MyData/@dataBeginDate, '-', '')"> 

이상 명시 적으로 :

<sch:assert test="number(translate(@value, '-', '')) > number(translate(//MyData/@dataBeginDate, '-', ''))">
