元素必须没有字符或元素信息项[children]，因为类型的内容类型为空 [英] Element must have no character or element information item [children], because the type's content type is empty

问题描述

当我从事这个项目时，我不断收到一条错误消息:

As I work on this project I keep getting an error saying:

元素客户"必须没有字符或元素信息项[children]，因为该类型的内容类型为空.

Element 'Customer' must have no character or element information item [children], because the type's content type is empty.

我不知道为什么这不起作用，因为我按照说明进行操作，看起来像这样:

I am not sure why this is not working seeing I followed the notes and it looks like this:

<xs:element name="Customer" type="xs:string">  
  <xs:complexType>  
    <xs:attribute name="id" type="xs:integer" use="required"/>  
  </xs:complexType>  
</xs:element>

我知道它是说我不能在其中包含 type="xs:string" 但是我如何让它必须有一个字符串?

I know it's saying I can't have the type="xs:string" in there but then how do I make it have to have a string?

推荐答案

您需要修复 XSD 的 Customer 定义:将 xs:simpleContent 与 一起使用>xs:complexType 而不是您定义中的 xsl:element/@type (customer.xsd):

You'll need to fix your XSD's definition of Customer: Use xs:simpleContent with xs:complexType rather than xsl:element/@type in your definition (customer.xsd):

<?xml version="1.0" encoding="utf-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
           version="1.0">
  <xs:element name="Customer">
    <xs:complexType>
      <xs:simpleContent>
        <xs:extension base="xs:string">
          <xs:attribute name="id" type="xs:integer" use="required"/>
        </xs:extension>
      </xs:simpleContent>
    </xs:complexType>
  </xs:element>
</xs:schema>

上面的XSD然后会认为如下内容有效:

The above XSD will then consider content such as the following valid:

<Customer id="123">This is a string.</Customer>
