Question

I need to write a XSD which will validate the attribute as well as the value of the element. So far I am able to validate the attributes but not the value. Thanks for your help in advance.

My XML:

<params>
    <param dataType="java.lang.String">12A</param>
    <param dataType="java.lang.Integer">6455</param>
    <param dataType="oracle.jbo.domain.Date">2014-10-01</param>
    <param dataType="oracle.jbo.domain.Date">2018-10-01</param>
    <param dataType="java.lang.String">H1</param>
    <param dataType="java.lang.String">4235AS</param>
    <param dataType="java.lang.String">5aZ</param>
    <param dataType="java.lang.String">q2w</param>
    <param dataType="java.lang.Integer">10</param>
    <param dataType="java.lang.Integer">3</param>
</params>

My XSD

<?xml version="1.0"?>
<xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" 
           xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <xs:element name="params">
    <xs:complexType>
      <xs:sequence>
        <xs:element maxOccurs="10" 
                    name="param" type="paramType" />
      </xs:sequence>
    </xs:complexType>
  </xs:element>

  <xs:complexType name="paramType">
    <xs:simpleContent>
      <xs:extension base="xs:string">
        <xs:attribute name="dataType" type="validAttributeType" use="optional" />
      </xs:extension>
    </xs:simpleContent>
  </xs:complexType>

  <xs:simpleType name="validAttributeType">
    <xs:restriction base="xs:string">
      <xs:enumeration value="java.lang.String" />
      <xs:enumeration value="java.lang.Integer" />
      <xs:enumeration value="oracle.jbo.domain.Date" />

    </xs:restriction>
  </xs:simpleType>
</xs:schema>

So my need is, if the dataType says Integer it should only accept numbers as value or if it says date, then the value should be date not anything else.

XSD 1.0

无法在XSD 1.0中完成基于属性值的类型检查。

XSD 1.1

您可以使用 Condition Type Assignment ：

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
           elementFormDefault="qualified"
           xmlns:vc="http://www.w3.org/2007/XMLSchema-versioning"
           vc:minVersion="1.1">

  <xs:element name="params">
    <xs:complexType>
      <xs:sequence>
        <xs:element maxOccurs="10" name="param">
          <xs:alternative test="@dataType='java.lang.String'" type="xs:string"/> 
          <xs:alternative test="@dataType='java.lang.Integer'" type="xs:integer"/> 
          <xs:alternative test="@dataType='oracle.jbo.domain.Date'" type="xs:date"/> 
        </xs:element>
      </xs:sequence>
    </xs:complexType>
  </xs:element>

</xs:schema>

虽然这是表示基于属性的类型的正确结构，但您应注意在某些情况下XSD类型可能与Java类型不同，因此请检查以确保根据您的要求可以容忍任何差异。
