xsd에서 속성을 참조하는 방법

Question

후속 요소 정의에서 참조 할 수있는 속성을 정의하려고했습니다.

<xs:attribute name="ridref" type="xs:string"/> 

나중에 나는이처럼 사용

<xs:element name="coordRegRef"> 
    <xs:complexType> 
    <!--xs:attribute name="ridref" type="xs:string"/ this works but I want to use ref --> 
    <xs:attribute ref="ridref" use="required"/> 
    </xs:complexType> 
</xs:element> 

XSD는 xmllint가

xmllint --schema pc-ar.xsd pc-ar.xml 

으로 잘 컴파일하지만 xmllint가 내가 의미로 해석

pc-ar.xml:41: element coordRegRef: Schemas validity error : Element '{http://pc-ar.xsd}coordRegRef', attribute 'ridref': The attribute 'ridref' is not allowed. 
pc-ar.xml:41: element coordRegRef: Schemas validity error : Element '{http://pc-ar.xsd}coordRegRef': The attribute '{http://pc-ar.xsd}ridref' is required but missing. 

을 말한다 내 XML 파일은 네임 스페이스를 사용해야합니다. 대신

<coordRegRef ridref="111"/> 

왜

의 ridref

<coordRegRef fix:ridref="111"/> 

(하지 작동하지만 원치 않는)을 검색 하시나요?

Answer 1

네임 스페이스에서.

이유는 XML 스키마에서 모든 전역 요소, 특성 또는 형식 정의가 정규화되어야한다는 것입니다. 따라서 attributeFormDefault="unqualified"으로 설정 한 경우에도 전역 적으로 정의 된 모든 속성의 접두사는 네임 스페이스가됩니다. 해결 방법은 이러한 속성을 <xs:attributeGroup> (또는 전역 유형) 내에 혼자 정의하는 것입니다. 이 경우 속성 그룹의 이름은 내부에있는 속성의 이름 대신 네임 스페이스가 첨부됩니다. 그런 다음 ref을 사용하여 해당 특성 그룹을 참조하고 네임 스페이스에 있지 않아도 전역 적으로 사용할 수있는 특성을 얻을 수 있습니다.

Answer 2

전역 속성을 선언하기 때문에이 이름은 {http://pc-ar.xsd} 네임 스페이스의 일부입니다. XML의 접두어가없는 속성은 항상 네임 스페이스에 속하지 않습니다.

<xs:attributeGroup name="required-ridref"> 
    <xs:attribute name="ridref" type="xs:string" use="required"/> 
</xs:attributeGroup> 
<xs:attributeGroup name="not-required-ridref"> 
    <xs:attribute name="ridref" type="xs:string" use="required"/> 
</xs:attributeGroup> 

을 그리고 어디를 그룹을 참조 : 로컬 속성을 선언하고, 또한 XML의 특성을 앞에 싶지 않아 원하지 않는 경우에 따라서, 대안 atrribute 그룹 내부를 래핑하는 것입니다 속성 참조 할 것 :

<xs:element name="coordRegRef"> 
    <xs:complexType> 
     <xs:attributeGroup ref="required-ridref" /> 
    </xs:complexType> 
</xs:element> 

<xs:element name="assetRegRef"> 
    <xs:complexType> 
     <xs:sequence> 
      <xs:element name="ridref2" type="xs:string"/> 
     </xs:sequence> 
     <xs:attributeGroup ref="not-required-ridref"/> 
    </xs:complexType> 
</xs:element>
