Question

我想从现有的模式文件中重新定义一些复杂的类型。当我使用Altova XMLSpy报告错误时。它显示：

重新定义类型定义“地址”必须是其自身的扩展或限制。错误位置：xs：schema / xs：redefine / xs：complexType / xs：complexContent / xs：extension / @base 细节 src-redefine.5：重新定义类型定义“地址”必须是其自身的扩展或限制。

源代码中已经有<xs:extension>部分。

<xs:redefine schemaLocation="reusable.xsd">
  <xs:complexType name="Address">
    <xs:complexContent>
      <xs:extension  base="Address">
        <xs:sequence>
          <xs:element name="PostCode"/>
        </xs:sequence>
      </xs:extension>
    </xs:complexContent>
  </xs:complexType>
</xs:redefine>

我无法弄清楚它有什么问题。这是我的架构文件的源代码。

Source.xsd

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" targetNamespace="we:love:xml:schemas:but:we:hate:namespaces">
  <xs:redefine schemaLocation="reusable.xsd">
    <xs:complexType name="Address">
      <xs:complexContent>
        <xs:extension base="Address">
          <xs:sequence>
            <xs:element name="PostCode" />
          </xs:sequence>
        </xs:extension>
      </xs:complexContent>
    </xs:complexType>
  </xs:redefine>
  <xs:element name="resume">
    <xs:annotation>
      <xs:documentation>Comment describing your root element</xs:documentation>
    </xs:annotation>
  </xs:element>
</xs:schema>

提前致谢。

            <xs:documentation>This is a type meant to represent a generic address. It consists of an

                country. It is suggested that if need be, on a transform use conditional processing

Answer 1

您选择的名称空间URI就是这么说的。你不想扩展“地址”，你想扩展“wlxsbwhns：Address”，其中前缀wlxsbwhns绑定到你的目标命名空间URI。

XML Schema <xs：redefine> </xs：redefine>有问题
