为什么我会收到此错误“xml 中元素目录的内容无效”？

Question

描述资源路径位置类型 cvc-complex-type.2.4.a：从元素“os:catalog”开始发现无效内容。需要 '{"http://www.example.org/objectshop":CatalogType}' 之一。 objectshop.xml /HelloWorld/WebContent 第 6 行 XML 问题

Answer 1

您的 XSD 文件应该具有如下格式的 XML 文件

<os:objectshop>
  <os:CatalogType>
    ...
  </os:CatalogType>
  <os:MembersType>
    ...
  </os:MembersType>
</os:objectshop>

例如定义在

 <complexType name="ObjectShopType">
  <sequence>
    <element name="CatalogType" type="os:CatalogType"></element>
    <element name="MembersType" type="os:MembersType"></element>
  </sequence>
</complexType>

我建议更新您的架构以替换

<complexType name="CatalogType">
    <sequence>
      <element name="ProductType" type="os:ProductType" minOccurs="0" maxOccurs="unbounded"/>
    </sequence>
  </complexType>
  <complexType name="ObjectShopType">
    <sequence>
      <element name="CatalogType" type="os:CatalogType"/>
      <element name="MembersType" type="os:MembersType"/>
    </sequence>
  </complexType>

与

<complexType name="CatalogType">
    <sequence>
      <element name="product" type="os:ProductType" minOccurs="0" maxOccurs="unbounded"/>
    </sequence>
  </complexType>
  <complexType name="ObjectShopType">
    <sequence>
      <element name="catalog" type="os:CatalogType"/>
      <element name="membership" type="os:MembersType"/>
    </sequence>
  </complexType>
