在complexType中嵌套simpleType

Question

以下代碼在驗證期間給我提供以下錯誤。這是否意味着我無法在complexType元素中嵌套simpleType元素？

Error - Line 18, 17: org.xml.sax.SAXParseException; lineNumber: 18; columnNumber: 17; s4s-elt-must-match.1: The content of 'sequence' must match (annotation?, (element | group | choice | sequence | any)*). A problem was found starting at: simpleType.

<?xml version="1.0" encoding="UTF-8"?> 
<schema xmlns="http://www.w3.org/2001/XMLSchema" 
    targetNamespace="http://www.example.org/carType" 
    elementFormDefault="qualified"> 

    <element name="carType"> 
     <complexType> 
      <sequence> 
       <simpleType name="colour"> 
        <restriction base="string"> 
         <enumeration value="blue" /> 
         <enumeration value="yellow" /> 
         <enumeration value="green" /> 
         <enumeration value="black" /> 
         <enumeration value="white" /> 
        </restriction> 
       </simpleType> 
       <simpleType name="body"> 
        <restriction base="string"> 
         <enumeration value="sedan" /> 
         <enumeration value="hatchback" /> 
        </restriction> 
       </simpleType> 
      </sequence> 
     </complexType> 
    </element> 
</schema> 

Answer 1

你靠近。只是讓兩個小調整到您的XSD：

1. 如果你有<simpleType name="colour">，而不是聲明 colour元素：

   <element name="colour"> 
        <simpleType> 
   

2. 同樣，如果你有<simpleType name="body">，而不是 聲明body元素：

   <element name="body"> 
        <simpleType> 
   

共有，則：

<?xml version="1.0" encoding="UTF-8"?> 
<schema xmlns="http://www.w3.org/2001/XMLSchema" 
     targetNamespace="http://www.example.org/carType" 
     elementFormDefault="qualified"> 
    <element name="carType"> 
    <complexType> 
     <sequence> 
     <element name="colour"> 
      <simpleType> 
      <restriction base="string"> 
       <enumeration value="blue" /> 
       <enumeration value="yellow" /> 
       <enumeration value="green" /> 
       <enumeration value="black" /> 
       <enumeration value="white" /> 
      </restriction> 
      </simpleType> 
     </element> 
     <element name="body"> 
      <simpleType> 
      <restriction base="string"> 
       <enumeration value="sedan" /> 
       <enumeration value="hatchback" /> 
      </restriction> 
      </simpleType> 
     </element> 
     </sequence> 
    </complexType> 
    </element> 
</schema>
