Question

我有一个简单的XML文件，我想针对XSD进行验证。当我使用一些随机验证器进行验证时，我总是会收到以下错误：

从元素'Entities'开始，找到了无效的内容。预计会有一个“{Entities}”。

这是XML：

<BusinessModel xmlns="http://schemas.testxyzxyz.de/xyz/BusinessModel" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<Entities>
    <Entity Name="Customer">
        <Attribute Name="Forename" Type="String" />
        <Attribute Name="Surname" Type="String" />
        <Attribute Name="Birthday" Type="Date" />
    </Entity>
</Entities>
</BusinessModel>

和XSD一样：

<?xml version="1.0"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
        targetNamespace="http://schemas.testxyzxyz.de/xyz/BusinessModel"
        xmlns="http://schemas.testxyzxyz.de/xyz/BusinessModel">

<xsd:element name="BusinessModel" type="BusinessModelType" />

<xsd:complexType name="BusinessModelType">
    <xsd:choice minOccurs="0" maxOccurs="unbounded">
        <xsd:element name="Entities" type="EntitiesType" />
    </xsd:choice>
</xsd:complexType>

<xsd:complexType name="EntitiesType">
    <xsd:sequence>
        <xsd:element name="Entity" type="EntityType" maxOccurs="unbounded" />
    </xsd:sequence>
</xsd:complexType>

<xsd:complexType name="AttributeType">
    <xsd:attribute name="Name" type="xsd:string" use="required" />
    <xsd:attribute name="Type" type="xsd:string" use="required" />
</xsd:complexType>

<xsd:complexType name="EntityType">
    <xsd:sequence>
        <xsd:element name="Attribute" type="AttributeType" maxOccurs="unbounded" minOccurs="1" />
    </xsd:sequence>
        <xsd:attribute name="Name" type="xsd:string" use="required" />
</xsd:complexType>
</xsd:schema>

从小时开始寻找这个问题，我仍然没有发现错误。你能发现我正确的方向吗？ ;）

Answer 1

XML Representation of Element Declaration Schema Components：

{目标命名空间}

如果form存在且其实际值为qualified，或者form不存在且实际值为elementFormDefault祖先上的<schema>为qualified，然后是父targetNamespace元素的<schema> [属性]的实际值信息项，或缺席（如果没有），否则缺席。

由于elemeFormDefault的默认值为unqualified，除非另有说明，否则本地元素必须是不合格的。

由于您设置了xmlns="http://schemas.testxyzxyz.de/xyz/BusinessModel"，因此Entities成为合格人员。修复是将elementFormDefault="qualified"设置为@polishchuk写道。

尝试此架构：

<?xml version="1.0"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" targetNamespace="http://schemas.testxyzxyz.de/xyz/BusinessModel" xmlns:b="http://schemas.testxyzxyz.de/xyz/BusinessModel">
  <xsd:element name="BusinessModel" type="b:BusinessModelType" />
  <xsd:complexType name="BusinessModelType">
    <xsd:choice minOccurs="0" maxOccurs="unbounded">
      <xsd:element name="Entities" type="b:EntitiesType" />
    </xsd:choice>
  </xsd:complexType>
  <xsd:complexType name="EntitiesType">
    <xsd:sequence>
      <xsd:element name="Entity" type="b:EntityType" maxOccurs="unbounded" />
    </xsd:sequence>
  </xsd:complexType>
  <xsd:complexType name="AttributeType">
    <xsd:attribute name="Name" type="xsd:string" use="required" />
    <xsd:attribute name="Type" type="xsd:string" use="required" />
  </xsd:complexType>
  <xsd:complexType name="EntityType">
    <xsd:sequence>
      <xsd:element name="Attribute" type="b:AttributeType" maxOccurs="unbounded" minOccurs="1" />
    </xsd:sequence>
    <xsd:attribute name="Name" type="xsd:string" use="required" />
  </xsd:complexType>
</xsd:schema>
