maxoccurs / minoccurs在哪里指定？ [英] maxoccurs/minoccurs where to specify?

问题描述

您好我们有xsd如下

 
  < xsd：element    名称  =  " books"  >   
  < xsd：complexType>   
  < xsd：sequence     minOccurs   =  " 1"     maxOccurs   =  " unbounded"  >     
  < xsd：element    参考  =  " book1"     minOccurs   =  " 1"     maxOccurs   =  " unbounded"   />     
 
   < xsd：element     ref   =  " book2"     minOccurs   =  " 1"     maxOccurs   =  " unbounded"   />  
 
 < / xsd：sequence>  
 
  < / xsd：complexType>  
 < / xsd：element>   
 
     
 
  这是否符合  
 
     
  < books>   
  < BOOK1 /><第二册>< BOOK1 /><第二册/>< BOOK1 /><第二册/>< BOOK1 /><第二册/ > ..   
  < / books>   
     
 
  或  
 
  < books>   
  < book1 />< book2>   
  < / books>   
 
     
  < books>   
  < book1 />< book2>   
  < / books>   
     
 
  pl指定正确的结果&为什么？ 
 
     
 

解决方案

正确的结果将是

< books> 
 
< book1 /> 
 
< book1 /> 
 
< book2 /> 
 
< book2 /> ; 
 
 
 
< / books> 
 
< books> 
 
< book1 /> 
 
< book1 /> 
 
< book2 /> 
 
< book2 /> 
 
 
 
< / books>

Hi we have xsd as follows

<xsd:element name="books">
  <xsd:complexType>
    <xsd:sequence minOccurs="1" maxOccurs="unbounded"> 
      <xsd:element ref="book1" minOccurs="1" maxOccurs="unbounded"/> 
	<xsd:element ref="book2" minOccurs="1" maxOccurs="unbounded"/>
</xsd:sequence>
  </xsd:complexType>
</xsd:element>
Will this be complied as 
<books>
  <book1/><book2><book1/><book2/><book1/><book2/><book1/><book2/>..
</books>
OR 
<books>
  <book1/><book2>
</books>
<books>
  <book1/><book2>
</books>
pl specify the correct result & why?

解决方案

The Correct Result would be

<books>

<book1 />

<book1 />

<book2 />

<book2 />



</books>

<books>

<book1 />

<book1 />

<book2 />

<book2 />



</books>
