我有一个奇怪的情况,让我有点困惑......
我有一个 XML 数据文件,我试图针对一个模式进行验证,该模式似乎会根据所使用的解析器给出不同的结果。不知道我做错了什么或如何更好地表示模式中的约束,以便所有解析器都可以正确验证 XML ......这是模式问题部分的片段:
<xsd:element name="DemoValues">
<xsd:annotation>
<xsd:documentation>Demo values for any, or all, of the demo categories defined on the GAP . A
demo value includes a reference to the category it applies to, a value in the appropriate
format and an optional market reference if it is for a specific market. If the market
reference is omitted the demo value applies to the entire area serviced by the outlet. Each
demo category may only have a single demo value within this group of demo values. However if
the demo value is for a market, there may be a demo value per market within this group of
demo values. </xsd:documentation>
</xsd:annotation>
<xsd:complexType>
<xsd:sequence>
<xsd:element name="DemoValue" type="gap:demoValueType" maxOccurs="unbounded"/>
</xsd:sequence>
</xsd:complexType>
<xsd:unique name="DemoValueConstraint">
<xsd:annotation>
<xsd:documentation>Constraint allows only up to one demo value for a demo category, and per
market when a market reference exists. </xsd:documentation>
</xsd:annotation>
<xsd:selector xpath="gap:DemoValue"/>
<xsd:field xpath="@demoRef"/>
<xsd:field xpath="@marketRef|@demoRef"/>
</xsd:unique>
这是有问题的 XML:
<DemoValues>
<DemoValue demoRef="DM0" marketRef="MKT1">0.40</DemoValue>
<DemoValue demoRef="DM1">15.00</DemoValue>
</DemoValues>
产生此错误:
元素“{http://www.AAAA.org/schemas/canadianTVAP}DemoValue”,属性“marketRef”:唯一标识约束字段的 XPath '@marketRef|@demoRef''{http://www. AAAA.org/schemas/canadianTVGAP}DemoValueConstraint' 评估为具有多个成员的节点集。
简化错误是:字段“marketRef”最多期望一个值。
xml 的目的是允许所有这些组合:
1)
<DemoValues>
<DemoValue demoRef="DM0" marketRef="MKT1">0.40</DemoValue>
<DemoValue demoRef="DM1">15.00</DemoValue>
</DemoValues>
2)
<DemoValues>
<DemoValue demoRef="DM0" marketRef="MKT1">0.40</DemoValue>
<DemoValue demoRef="DM0" marketRef="MKT2">0.41</DemoValue>
<DemoValue demoRef="DM0" marketRef="MKT3">0.42</DemoValue>
<DemoValue demoRef="DM0" marketRef="MKT4">0.43</DemoValue>
<DemoValue demoRef="DM1">15.00</DemoValue>
</DemoValues>
3)
<DemoValues>
<DemoValue demoRef="DM0" marketRef="MKT1">0.40</DemoValue>
<DemoValue demoRef="DM1" marketRef="MKT1">0.41</DemoValue>
<DemoValue demoRef="DM2" marketRef="MKT1">0.42</DemoValue>
<DemoValue demoRef="DM3">15.00</DemoValue>
</DemoValues>
谢谢你的帮助!!
