XSD 错误:类型未声明,或不是简单类型 [英] XSD Error: Type is not declared, or is not a simple type
问题描述
对于这个解释,我使用了 2 个不同的 XSD:
For this explanation I am using 2 different XSDs:
customEntry.xsd:
<?xml version="1.0" encoding="utf-8"?>
<xs:schema id="customEntry"
targetNamespace="http://tempuri.org/customEntry.xsd"
elementFormDefault="qualified"
xmlns="http://tempuri.org/customEntry.xsd"
xmlns:mstns="http://tempuri.org/customEntry.xsd"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
>
<xs:simpleType name="customEntry">
<xs:restriction base="xs:string">
<xs:pattern value="[A-Za-z0-9_%./]*"/>
</xs:restriction>
</xs:simpleType>
</xs:schema>
element_ArtStyleSuffix.xsd:
<?xml version="1.0" encoding="utf-8"?>
<xs:schema id="element_ArtStyleSuffix"
targetNamespace="http://tempuri.org/element_ArtStyleSuffix.xsd"
elementFormDefault="qualified"
xmlns="http://tempuri.org/element_ArtStyleSuffix.xsd"
xmlns:mstns="http://tempuri.org/element_ArtStyleSuffix.xsd"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
>
<xs:import namespace="http://tempuri.org/customEntry.xsd" schemaLocation="customEntry.xsd"/>
<!-- Civilizations ArtStyleSuffix Enumeration -->
<xs:simpleType name="enum_ArtStyleSuffix">
<xs:restriction base="xs:string">
<xs:enumeration value="_EURO"/>
<xs:enumeration value="_AFRI"/>
<xs:enumeration value="_AMER"/>
<xs:enumeration value="_ASIA"/>
</xs:restriction>
</xs:simpleType>
<!-- ArtStyleSuffix GameData Schema Information -->
<xs:element name="GameData">
<xs:complexType>
<xs:all>
<xs:element minOccurs="0" maxOccurs="1" name="ArtStyleSuffix">
<xs:annotation>
<xs:documentation>
Select a default ArtStyleSuffix or you may create your own custom one and place its TypeName here.
</xs:documentation>
</xs:annotation>
<xs:simpleType>
<xs:union memberTypes="customEntry enum_ArtStyleSuffix"/>
</xs:simpleType>
</xs:element>
</xs:all>
</xs:complexType>
</xs:element>
</xs:schema>
我的问题在于以下行:
<xs:union memberTypes="customEntry enum_ArtStyleSuffix"/>
Visual Studio 2015 社区抛出错误:
Visual Studio 2015 community is throwing the error:
输入'http://tempuri.org/element_ArtStyleSuffix.xsd:customEntry' 是未声明,或者不是简单类型.
对我来说它看起来像一个简单的类型,我认为导入行声明了它,所以也许我不完全理解导入",因为我没有从导入行收到任何错误,只是联合行.我这样做正确吗?
It looks like a simple type to me and I thought the import line declared it, so maybe I don't understand "import" fully cause I'm not receiving any errors from the import line just the union line. Am I doing this correctly?
推荐答案
确实是一个简单的类型.但是,它并未在当前 XSD 的目标命名空间中声明;它在导入的 XSD 的命名空间中声明.在导入的 http://tempuri.org/customEntry.xsd
命名空间中引用 customEntry
以消除错误...
It is indeed a simply type. However, it is not declared in the target namespace of the current XSD; it's declared in the namespace of the imported XSD. Reference customEntry
in the imported http://tempuri.org/customEntry.xsd
namespace to eliminate the error...
具体来说,在主 XSD 的 xs:schema
元素上声明一个命名空间前缀:
Specifically, declare a namespace prefix on the xs:schema
element of your main XSD:
xmlns:ce="http://tempuri.org/customEntry.xsd"
以便您可以在 xs:union
声明中使用它:
so that you can use it in your xs:union
declaration:
<xs:union memberTypes="ce:customEntry enum_ArtStyleSuffix"/>
你的错误就会消失.
附注:这是可以接受的,但既不要求也不习惯将命名空间命名为 XSD 文件的 URL;考虑删除 .xsd
扩展名.
Side note: It's acceptable, but neither required nor conventional to name your namespaces as URLs to XSD files; consider dropping the .xsd
extension.
